An upcoming PSP firmware change will allow coreboot to load the two
SMU firmware blobs (one runs in SRAM and the other in DRAM). The
traditional method is for the PSP to control most of the process,
e.g. loading the SRAM version prior to releasing the x86 reset.
Add a new command that can instruct the PSP to load a firmware blob
from a location in the flash.
The definition for commands 19 and 1a differ from others in that they
do not use a command/response buffer. Instead, the PSP will look in
the command/response pointer registers directly for the blob's
address.

The correct code needs to have the array index inverted relative to the
