Populate a memory_info struct with PEI and SPD data,
in order to inject the CBMEM_INFO table necessary to
populate a type17 SMBIOS table.
On Broadwell, this is done by the MRC binary, but the older
Haswell MRC binary doesn't populate the pei_data struct with
all the info needed, so we have to pull it from the SPD.
Some values are hardcoded based on platform specifications.

Some vendors store lower frequency profiles in the regular SPD,
if the SPD contains a XMP profile. To make use of the board's and DIMM's
maximum supported DRAM frequency, try to parse the XMP profile and
use it instead.
Validate the XMP profile to make sure that the installed DIMM count
per channel is supported and the requested voltage is supported.
To reduce complexity only XMP Profile 1 is read.
Allows my DRAM to run at 800Mhz instead of 666Mhz as encoded in the
default SPD.

MRS commands are used to tell the DRAM chip what timing and what
termination and drive strength to use, along with other parameters.
The MRS commands are defined by the DDR3 specification [1]. This
makes MRS commands hardware-independent.
MRS command creation is duplicated in various shapes and forms in any
chipset that does DDR3. This is an effort to create a generic MRS API
that can be used with any chipset.
This is used in the VX900 branch.
