Add support for sending debug output to an I/O port.
It can be used together with QEMU's isa-debugcon driver to log the
coreboot output to a file. The port is configurable and defaults
to 0x402 which has established as the de facto standard. For example,
SeaBIOS+OVMF [1] use that one too.

This option has never had much if any use. It solved a problem over 10
years ago that resulted from an argument over the value or lack thereof
of including all the debug strings in a coreboot image. The answer is
in: it's a good idea to maintain the capability to print all messages,
for many reasons.
This option is also misleading people, as in a recent discussion, to
believe that log messges are controlled at build time in a way they are
not. For the record, from this day forward, we can print messages at all
log levels and the default log level is set at boot time, as directed by
DEFAULT_CONSOLE_LOGLEVEL. You can set the default to 0 at build time and
if you are having trouble override it in CMOS and get more messages.
Besides, a quick glance shows it's always set to max (9 in this case) in
the very few cases (1) in which it is set.

There are assumptions that COLLECT_TIMESTAMPS and CONSOLE_CBMEM
rely on EARLY_CBMEM_INIT. This isn't true in the face of
DYNAMIC_CBMEM as it provides the same properties as EARLY_CBMEM_INIT.
Therefore, allow one to select COLLECT_TIMESTAMPS and CONSOLE_CBMEM
when DYNAMIC_CBMEM is selected. Lastly, don't hard code the cbmem
implementation when COLLECT_TIMESTAMPS is selected.

The console drivers (especially serial drivers) in Kconfig were named in
different styles. This change will rename configuration names to a better naming
style.
- EARLY_CONSOLE:
Enable output in pre-ram stage. (Renamed from EARLY_SERIAL_CONSOLE
because it also supports non-serial)
- CONSOLE_SERIAL:
Enable serial output console, from one of the serial drivers. (Renamed
from SERIAL_CONSOLE because other non-serial drivers are named as
CONSOLE_XXX like CONSOLE_CBMEM)
- CONSOLE_SERIAL_UART:
Device-specific UART driver. (Renamed from
CONSOLE_SERIAL_NONSTANDARD_MEM because it may be not memory-mapped)
- HAVE_UART_SPECIAL:
A dependency for CONSOLE_SERIAL_UART.
Verified to boot on x86/qemu and armv7/snow, and still seeing console
messages in romstage for both platforms.

This patch makes pre-RAM serial init more generic, particularly for
platforms which do not necessarily need cache-as-RAM in order to use
the serial console and do not have a standard 8250 serial port.
This adds a Kconfig variable to set romstage-* for very early serial
console init. The current method assumes that cache-as-RAM should
enable this, so to maintain compatibility selecting CACHE_AS_RAM will
also select EARLY_SERIAL_CONSOLE.
The UART code structure needs some rework, but the use of ROMCC,
romstage, and then ramstage makes things complex.
uart.h now includes all .h files for all uarts. All 2 of them.
This is actually a simplifying change.

This adds more configurability to POST codes. The current assumption
is that POST codes should be written to an IO port (e.g. LPC) if POST
codes are enabled. This changes the assumption so that POST codes can
be written to the serial console without being written to an IO port.
This enables POST codes by default using "default y" to avoid
changing current behavior.
