requests are not cleared until kernel verification stage is

Kconfig options for both SGX and the corresponding PRMRR size.
The PRMRR size Kconfig has been implemented as a maximum value. At
runtime the final PRMRR size gets selected by checking the supported
values in MSR_PRMRR_VALID_CONFIG and trying to select the value nearest
to the chosen one.
When "Maximum" is chosen, the highest possibly value from the MSR gets
used. When a too strict limit is set, coreboot will die, printing an

Instead of doing our own calculations, rely on TOLUM returned by FSP
for cbmem_top. This (hopefully) saves us from making mistakes in weird
calculations of offsets and alignments.
Further this makes it easier to implement e.g. SGX PRMRR size selection
via Kconfig as we do not have to make any assumptions about alignments
but can simply pass (valid) values to FSP.

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.
