EWL (Enhanced Warning Log) is a FSP HOB generated by FSP-M that may
contain several warnings/errors related to core, uncore and memory, etc.
mainboard can override it in its romstage.c for its own
Enhanced Warning Log check.

This patch introduces a config option for SoC code to choose
the applicable SoC workaround.
For now, we have introduced `SOC_INTEL_UFS_OCP_TIMER_DISABLE`
to apply UFS OCP timeout disable workaround.
At present ADL SoC only selects so, and in future MTL and others
should check with Intel prior selecting this kconfig.
It's the placeholder to add more workaround in required going forward.

After some measurements it turned out that Elkhart Lake uses a higher
CSR clock internally from which the MDIO clock is derived. In order to
stay compliant with the specification, the MDIO clock needs to be lower
than 2.5 MHz. Therefore, the divider needs to be 102 and not 62.
This patch changes the define to match the new divider value and uses
this new define at the appropriate place.
Test=Measure the MDIO clock rate on mc_ehl2 which results in 2 MHz.

Depending on the real workload that is executed on the system the L1
prefetcher might be too aggressive and will populate the L1 cache ahead
with data that is not really needed. In the end, this will result in a
higher cache miss rate thus slowing down the real application.
This patch provides a devicetree option to disable the L1 prefetcher if
needed. This can be requested on mainboard level if needed.

For recent X86 CPUs, the 0x15 CPUID instruction will return Time Stamp
Counter Frequence. For CPUs that do not support this instruction, EDK2
must include a different library which is the reason why this must be
configured at build time.
If this is enabled, and the CPU doesn't support 0x15, it will fail to
boot. If is not enabled, and the CPU does support 0x15, it will still
boot but without support for the leaf. Consequently, disabled it by
default.

On nissa, the pre-x86 time is not part of the 1s firmware boot time
target. Including the pre-x86 timestamps causes confusion since the boot
time appears to be greater than 1s, so disable the Kconfig on nissa.
We're not doing any analysis or optimisation of the pre-x86 time on
nissa anyway, this work will start from MTL onwards. Also, the Kconfig
is already disabled on the brya firmware branch, so this will result in
the same behaviour as brya.
