The assumption up to this point was that if the system had an x86
processor, verstage would be running on the x86 processor. With running
verstage on the PSP, that assumption no longer holds true, so exclude
pieces of code that cause problems for verstage on the PSP.
This change will add these files to verstage only if the verstage
architecture is X86 - either 32 or 64 bit.

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 is needed in a follow-on patch to enable udelay() handling on
apollolake, which is a dependency for the console code.

To support x86 verstage one needs a working buffer for
vboot. That buffer resides in the cache-as-ram region
which persists across verstage and romstage. The current
assumption is that verstage brings cache-as-ram up
and romstage tears cache-as-ram down. The timestamp,
cbmem console, and the vboot work buffer are persistent
through in both romstage and verstage. The vboot
work buffer as well as the cbmem console are permanently
destroyed once cache-as-ram is torn down. The timestamp
region is migrated. When verstage is enabled the assumption
is that _start is the romstage entry point. It's currently
expected that the chipset provides the entry point to
romstage when verstage is employed. Also, the car_var_*()
APIs use direct access when in verstage since its expected
verstage does not tear down cache-as-ram. Lastly, supporting
files were added to verstage-y such that an x86 verstage
will build and link.

Some boards use the local apic for udelay(), but they also provide
their own implementation of udelay() for SMM. The reason for using
the local apic for udelay() in ramstage is to not have to pay the
penalty of calibrating the TSC frequency. Therefore provide a
TSC_CONSTANT_RATE option to indicate that TSC calibration is not
needed. Instead rely on the presence of a tsc_freq_mhz() function
provided by the cpu/board. Additionally, assume that if
TSC_CONSTANT_RATE is selected the udelay() function in SMM will
be the tsc.

at the same time let the user specify sources instead
of object files:
- objs becomes ramstage-srcs
- initobjs becomes romstage-srcs
- driver becomes driver-srcs
- smmobj becomes smm-srcs
The user servicable parts are named accordingly:
ramstage-y, romstage-y, driver-y, smm-y
Also, the object file names are properly renamed now, using
.ramstage.o, .romstage.o, .driver.o, .smm.o suffixes consistently.
Remove stubbed out via/epia-m700 dsdt/ssdt files - they didn't
easily fit in the build system and aren't useful anyway.

tested. I also addressed questions raised by Uwe:
TSC_X86RDTSC_CALIBRATE_WITH_TIMER2
UDELAY_TSC
Are now defined as booleans in src/cpu/x86/Kconfig and can be selected in
the mainboard Kconfig. The remaining question of Uwe's is a deeper
problem:
---
We'll have to check if this works. From a quick glance
the Rumba does not have the mmx related lines (which _are_ in
Makefile.romccboard.inc, though):
crt0-y += ../../../../src/cpu/x86/fpu/enable_fpu.inc
crt0-y += ../../../../src/cpu/x86/mmx/enable_mmx.inc
crt0-y += auto.inc
crt0-y += ../../../../src/cpu/x86/mmx/disable_mmx.inc
---
We're going to need a whole variant of this standard mainboard OR
we're going to have to make (some) of the unconditional includes above
conditional.

- Whitespace fixes, remove trailing whitespace, use TABs for identation
(except in Kconfig "help" lines, which start with one TAB and two spaces
as per Linux kernel style)
- Kconfig: Standardize on 'bool' (not 'boolean').
- s/lar/cbfs/ in one Kconfig help string.
- Reword various Kconfig menu entries for a more usable and consistent menu.
- Fix incorrect comment of NO_RUN in devices/Kconfig.
- superio/serverengines/Kconfig: Incorrect config name.
- superio/Makefile.inc: s/serverengine/serverengines/.
- superio/intel/Kconfig: s/SUPERIO_FINTEK_I3100/SUPERIO_INTEL_I3100/.
- mainboard/via/vt8454c/Kconfig: Fix copy-paste error in help string.
- mainboard/via/epia-n/Kconfig: Fix "bool" menu text.
- console/Kconfig: Don't mention defaults in the menu string, kconfig
already displays them anyway.
- Kill "Drivers" menu for now, it only confuses users as long as it's emtpy.
