To avoid having to calculate the length of a struct separately, rework
the code to give the struct a tag name, so that `sizeof()` can be used
instead. This involves refactoring the `get_emi_eeprom_vpd()` function
to return a struct instead of a union, so callers can no longer access
the EEPROM data as an array of bytes without additional code, but this
array view is only used inside `get_emi_eeprom_vpd()` when reading the
data from EMI.

This patch avoids the redundant programming of SRAM BAR when
the SRAM PCI device is enabled. Rather read the PCH SRAM Base
Address Register while enabling crashlog feature.
Additionally, this patch relies on PCI enumeration to get the
SRAM BAR rather than hijacking the SPI temporary base address
which might have resulted in problems if SPI is disabled on
some platform with BAR being implemented.

Instead of using the PSTATE SSDT generated by binaryPI, use the common
AMD code by selecting SOC_AMD_COMMON_BLOCK_ACPI_CPU_POWER_STATE. To
match the SSDT from binaryPI, set ACPI_SSDT_PSD_INDEPENDENT to n. There
are two differences to the binaryPI SSDT: Now coreboot includes the C1
state in the _CST package instead of just having the kernel add this due
to the ACPI_FADT_C1_SUPPORTED bit being set and the address of the
PS_STS_REG P state status MSR is written to the corresponding field of
the _PCT package instead of being 0.

get_pstate_core_freq will return 0; in this case that shouldn't happen,
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.

the blobs (ME, GBE ...), that are usually placed below the BIOS Flashmap.
It can therefore easily happen that the placement of the blobs collides
with the placement of the BIOS region (e.g. if CBFS_SIZE is big enough).
The fmaptool can't catch that, since it does not know of the blobs
placement.
This patch basically maps the regions described in the IFD (Intel

A core voltage ID larger than 0xff shouldn't happen, since SVI2's core
VID is only 8 bit long. In order for making it more difficult to use
this function in a wrong way that results in a very wrong voltage being
returned, also return 0 for those invalid core VID values.
