soc/amd/common/psp_smi_flash: add RPMC command-specific data structures

Browse source 
Add the data structures used for the command buffers for the PSP SMI
commands to increment and request the state of the monotonic counters in
the SPI flash. These data structures are specific to the PSP SMI mailbox
interface and not the data structures from the RPMC specification. The
AGESA code was used as a reference.
