This will allow PSP verstage to write logs to the serial console. We
are no longer dependent on using a serial enabled PSP boot loader.
Ideally we would delete this psp printk and use the standard printk.
Since picasso doesn't currently support mapping the UART though, I'll
keep it for now.

Now that the console system itself will clearly differentiate loglevels,
it is no longer necessary to explicitly add "ERROR: " in front of every
BIOS_ERR message to help it stand out more (and allow automated tooling
to grep for it). Removing all these extra .rodata characters should save
us a nice little amount of binary size.
This patch was created by running
find src/ -type f -exec perl -0777 -pi -e 's/printk\(\s*BIOS_ERR,\s*"ERROR: /printk\(BIOS_ERR, "/gi' '{}' ';'
and doing some cursory review/cleanup on the result. Then doing the same
thing for BIOS_WARN with
's/printk\(\s*BIOS_WARNING,\s*"WARN(ING)?: /printk\(BIOS_WARNING, "/gi'

A common use case when running coreboot on production systems is that
only the CBMEM console (the one with the least impact on boot speed) is
enabled. In this case, some of the code in the console subsystem has no
effect. Due to the way it's all genericized over multiple consoles and
tied together with function pointers, not all of this can be
compile-time eliminated automatically, so this patch adds a little
helper to facilitate that. This results in roughly 200 (compressed)
bytes of savings per stage on an arm64 system.

In order to provide the same loglevel prefixes and highlighting that
were recently introduced for "interactive" consoles (e.g. UART) to
"stored" consoles (e.g. CBMEM) but minimize the amont of extra storage
space wasted on this info, this patch will write a 1-byte control
character marker indicating the loglevel to the start of every line
logged in those consoles. The `cbmem` utility will then interpret those
markers and translate them back into loglevel prefixes and escape
sequences as needed.
Since coreboot and userspace log readers aren't always in sync,
occasionally an older reader may come across these markers and not know
how to interpret them... but that should usually be fine, as the range
chosen contains non-printable ASCII characters that normally have no
effect on the terminal. At worst the outdated reader would display one
garbled character at the start of every line which isn't that bad.
(Older versions of the `cbmem` utility will translate non-printable
characters into `?` question marks.)

This patch adds ANSI escape sequences to highlight a log line based on
its loglevel to the output of "interactive" consoles that are meant to
be displayed on a terminal (e.g. UART). This should help make errors and
warnings stand out better among the usual spew of debug messages. For
users whose terminal or use case doesn't support these sequences for
some reason (or who simply don't like them), they can be disabled with a
Kconfig.
While ANSI escape sequences can be used to add color, minicom (the
presumably most common terminal emulator for UART endpoints?) doesn't
support color output unless explicitly enabled (via -c command line
flag), and other terminal emulators may have similar restrictions, so in
an effort to make this as widely useful by default as possible I have
chosen not to use color codes and implement this highlighting via
bolding, underlining and inverting alone (which seem to go through in
all cases). If desired, support for separate color highlighting could be
added via Kconfig later.

- It is used for the device to skip _OFF and _ON during device driver
reload.
- OFSK is used to skip _OFF Method at the end of device driver removal.
- ONSK is used to skip _ON Method at the beginning of driver loading.
- General flow use case:
1. Device driver is removed by 'rmmod' command.
2. Device _RST is called. _RST perform reset.
3. Device increments OFSK in _RST to skip the following _OFF invoked by
OSPM.
4. OSPM invokes _OFF at the end of driver removal.
5. _OFF sees OFSK and skips current execution and decrements OFSK so that
_OFF will be executed normally next time.
6. _OFF increments ONSK to skip the following _ON invoked by OSPM.
7. Device driver is reloaded by 'insmod/modprobe' command.
8. OSPM invokes _ON at the beginning of driver loading.
9. _ON sees ONSK and skip current execution and decrements ONSK so that
_ON will be executed normally next time.
- In normal case:
When suspend, OSPM invokes _OFF. Since OFSK is zero, the device goes
to deeper state as expected.
When resume, OSPM invokes _ON. Sinc ONSK is zero, the device goes
to active state as expected.
- Generated changes:

Implementation for setup_lapic() did two things -- call
enable_lapic() and virtual_wire_mode_init().
In PARALLEL_MP case enable_lapic() was redundant as it
was already executed prior to initialize_cpu() call.
For the !PARALLEL_MP case enable_lapic() is added to
AP CPUs.

When sending self an IPI, some instructions may be processed
before IPI is serviced. Spend some time doing nothing, to
avoid entering a printk() and acquiring console_lock and
dead-locking.

This avoids unnecessary passing of APIC ID parameter and
allows some minor optimisation for X2APIC mode.

The options X2APIC_ONLY and X2APIC_RUNTIME were already user-visible
choices in menuconfig, but the functionality was not actually provided
except for platforms where FSP presumably enabled X2APIC.
Add the logic and related logging for switching to X2APIC operation.
TEST: qemu-system-x86_64 -M Q35 -accel kvm -bios coreboot.rom -serial
stdio -smp 2
PARALLEL_MP, and either X2APIC_ONLY or X2APIC_RUNTIME, need to be
selected for the build of emulation/qemu-q35.
