tsc_freq.c gets built into all stages, but the tsc_freq_mhz function it
implements calls the get_pstate_0_reg function which was only built into
ramstage. Since tsc_freq_mhz was only called in ramstage, commit
2323acab6a ("soc/amd/stoneyridge: implement and use get_pstate_0_reg")
didn't cause the build to fail, but better factor out the P-state-
related utility functions into a separate compilation unit and include
it in all stages that also include tsc_freq.c.

All AMD SoCs with Zen-based CPU cores are already using timestamps based
on the TSC counter, so use the existing common infrastructure instead of
reimplementing it in a similar way.
The behavior of the code changes slightly, but results in identical
timestamps. The timestamp_get implementation in soc/amd/common/block/cpu
divided the result of rdtscll() in timestamp_get by the result of
tsc_freq_mhz() and didn't override the weak timestamp_tick_freq_mhz
implementation that returns 1. The non AMD specific code returns the
result of rdtscll() in timestamp_get, but returns tsc_freq_mhz() instead
of 1 in timestamp_tick_freq_mhz, so we still get the correct timestamps.
TEST=The raw timestamps printed on the serial console are now multiplied
by the expected factor of the TSC frequency in MHz.
TEST=Normalized timestamps printed on the serial console by the x86 code
don't change significantly on Mandolin when comparing before and after
this patch. A slight variation in the timestamps is expected. An example
would be:
Before: CPU_CLUSTER: 0 init finished in 630 msecs
After: CPU_CLUSTER: 0 init finished in 629 msecs
TEST=The calculations of the time spent in verstage on PSP before
entering the bootblock on Guybrush result in similar times when
multiplying the value before the patch with the TSC frequency in the
case with the patch applied. The raw values printed on the serial
console by the verstage on PSP use the 1us time base, but the timestamp
logs that end up in CBMEM will be fixed up to use the same time base as
the x86 part of coreboot.

TSC_DEFAULT_FREQ_MHZ will be used as frequency, since for the TSC
frequency it's better to err on the end of the expected frequency being
too high which will cause longer than expected delays instead of too
short delays.

When the code was made common in commit 8f7f4bf87a ("soc/amd/cezanne,
common: factor out CPPC code to common AMD SoC code"), the include guard
wasn't renamed accordingly, so do that now.

Picasso and Cezanne use the serial voltage ID 2 standard to communicate
the CPU voltage to the voltage regulator module on the mainboard, while
Mendocino, Phoenix and Glinda use the serial voltage ID 3 standard for
this. Both standards encode the voltage in a different way, so add the
serial VID version number to the defines to clarify for which version
the define is.

Mendocino uses the SVI3 standard for CPU core voltage control which uses
9 data bits instead of the 8 in the SVI2 case and also calculates the
actual voltages with a different formula. The Mendocino code uses the
correct formula since commit 8d2bfbce23 ("soc/amd/sabrina/acpi:
Correct VID decoding on Sabrina"), but the MSR definition in the PPR
hasn't been updated to show the additional bit. The definition of the
register that is mirrored by these MSRs descries this 9th CPU voltage ID
bit though. Since this bit is expected to be zero, this shouldn't cause
a change in behavior.

The _LO part in the definition names is a leftover from before moving to
the pstate_msr union access to the bitfield elements where it still
mattered if a bit was in the lower of higher half of the MSR. With the
mask-and-shift access to the two parts of the MSR being gone, the _LO
part in the name isn't useful any more and possibly a bit misleading, so
drop that part.

Since we already have and use the pstate_msr union in get_pstate_info,
also pass it directly to the get_pstate_core_freq and
get_pstate_core_power function calls avoids having to sort-of convert
the msr_t type parameter in the implementations of those two functions.
In amdblocks/cpu.h a forward declaration of the pstate_msr union is used
since soc/msr.h doesn't exist in the two pre-Zen SoCs that also include
amdblocks/cpu.h.

Add the pstate_msr union of a bitfield struct and a raw uint64_t to
allow easier access of the bitfields of the P state MSRs which will be
implemented in a following patch. PPR #57254 Rev 1.52 was used as a
reference. This patch adds and uses the cpu_vid_8 bit which is the 9th
bit of the voltage ID specified in the SVI3 spec. The way the CPU
frequency is encoded in the PSTATE MSR has changed compared to Phoenix,
so also update the comment in the SoC's Kconfig file that the selected
SOC_AMD_COMMON_BLOCK_TSC_FAM17H_19H is likely incompatible which will be
addressed in the future.
