PCI devices starting from 18 are processor configuration devices for each
node and are not a bus itself.
According to ACPI specification 6.3 section 6.1.5:
"... _HID object must be used to describe any device that will be
enumerated by OSPM. OSPM only enumerates a device when no bus enumerator
can detect the device ID. ... Use the _ADR object to describe devices
enumerated by bus enumerators other than OSPM."
PCI device 18 with its functions has a standard enumerator, which is PCI
enumerator so it needs a _ADR. Create a separate ACPI device for the
processor configuration space. This fixes the ACPI compliance problem
from CB:36318.

AMD: Dropping the _HID of PCI root bus doesn't work well and people
started to notice the breakage.
Intel: These platforms have a devicetree switch to choose between PCI
and ACPI modes. In the former case we need _ADR, but in the latter _HID
as the PCI devices are hidden.
The conflicting use of _ADR and _HID still needs to be fixed before
we can bump our IASL version.

Currently all stages that need cbmem need an implementation of a
cbmem_top function. On FSP and AGESA platforms this proves to be
painful and a pointer to the top of lower memory if often passed via
lower memory (e.g. EBDA) or via a PCI scratchpad register.
The problem with writing to lower memory is that also need to be
written on S3 as one cannot assume it to be still there. Writing
things on S3 is always a fragile thing to do.
A very generic solution is to pass cbmem_top via the program argument.
It should be possible to implement this solution on every
architecture.
Instead trying to figure out which files can be removed from stages
and which cbmem_top implementations need with preprocessor, rename all
cbmem_top implementation to cbmem_top_romstage.

The x86 timers are a bit of a mess. Cases where different stages use
different counters and timestamps use different counters from udelays.
The original intention was to only flip TSC_CONSTANT_RATE Kconfig
to NOT_CONSTANT_TSC_RATE. The name would be incorrect though, those
counters do run with a constant rate but we just lack tsc_freq_mhz()
implementation for three platforms.
Note that for boards with UNKNOWN_TSC_RATE=y, each stage will have a
slow run of calibrate_tsc_with_pit(). This is easy enough to fix with
followup implementation of tsc_freq_mhz() for the platforms.
Implementations with LAPIC_MONOTONIC_TIMER typically will not have
tsc_freq_mhz() implemented and default to UNKNOWN_TSC_RATE. However,
as they don't use TSC for udelay() the slow calibrate_tsc_with_pit()
is avoided.
Because x86/tsc_delay.tsc was using two different guards and nb/via/vx900
claimed UDELAY_TSC, but pulled UDELAY_IO implementation, we also switch
that romstage to use UDELAY_TSC.

This adds a common cbmem_top implementation to all coreboot target.
In romstage a static variable will be used to cache the result of
cbmem_top_romstage.
In ramstage if CONFIG_RAMSTAGE_CBMEM_TOP_ARG is set a global variable
needs to be populated by the stage entry with the value passed via the
calling arguments. if CONFIG_RAMSTAGE_CBMEM_TOP_ARG is not set the
same implementation as will be used as in romstage.

The i82801ix_early_init is now called both in the bootblock and
romstage. The rationale behind setting this up twice is to ensure
bootblock-romstage compatibility in the future if for instance VBOOT
is used.
This moves the console init to the bootblock.
The romstage now runs uncached. Adding a prog_run hooks to set up an
MTRR to cache the romstage will be done in a followup patch.
The default size of 64KiB is not modified for the bootblock as trying
to fit both EHCI and SPI flash debugging needs a more space and 64KiB
is the next power of 2 size that fits it.
