The devicetree is not made for user-choosable options, thus introduce
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
error message.

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.

Remove the calculation of the Reserved Intel MMIO Memory size from
systemagent and memmap, since it is not needed.
The size is used in SA to calculate the space between cbmem_top and TSEG
without DPR and Chipset Reserved Memory. Since this will always be equal
to 0, the reservation will be skipped and TSEG, DPR and Chipset Reserved
Memory will get reserved alltogether.
By reading the code and pratical testing we figured out that:
- TSEG - DPR - reserved - top_of_memory == 0
- TSEG - DPR - reserved == top_of_memory
This means the whole block will never reserve anything because it is
always 0. Hence the code can be removed for simplification.

This adds a small amount of runtime overhead, but is also very
dangerous, since it allows use of an unlimited amount of stack memory,
potentially leading to stack overflow. This is only worsened in
coreboot, which often has very little stack space to begin with. Citing
concerns like this, all instances of VLA's were recently removed from the
Linux kernel. In the immortal words of Linus Torvalds [0],
AND USING VLA'S IS ACTIVELY STUPID! It generates much more code, and
much _slower_ code (and more fragile code), than just using a fixed
key size would have done. [...] Anyway, some of these are definitely
easy to just fix, and using VLA's is actively bad not just for
security worries, but simply because VLA's are a really horribly bad
idea in general in the kernel.
This patch follows suit and zaps all VLA's in coreboot. Some of the
existing VLA's are accidental ones, and all but one can be replaced with
small fixed-size buffers. The single tricky exception is in the SPI
controller interface, which will require a rewrite of old drivers
to remove [1].

Some timeouts given were too small when serial console is enabled due to

In addition we usually don't know how long specific code runs and how
