FSP: Notify FSP of Platform Log ID after Host Initiated Reset Reload

Trigging a Host Initiated Reset (when the host detects the FSP has gone
out to lunch and should be rebooted), would cause "Unknown Command" messages
to appear in the OPAL log.

This patch implements those messages

How to trigger FSP RR(HIR):

$ putmemproc 300000f8 0x00000000deadbeef
s1	k0:n0:s0:p00
ecmd_ppc putmemproc 300000f8 0x00000000deadbeef

Log showing unknown command:
/ # cat /sys/firmware/opal/msglog | grep -i ,3
[  110.232114723,3] FSP: fsp_trigger_reset() entry
[  188.431793837,3] FSP #0: Link down, starting R&R
[  464.109239162,3] FSP #0: Got XUP with no pending message !
[  466.340598554,3] FSP-DPO: Unknown command 0xce0900
[  466.340600126,3] FSP: Unhandled message ce0900

The message we need to handle is "Get PLID after host initiated FipS
reset/reload". When the FSP comes back from HIR, it asks "hey, so, which
error log explains why you rebooted me?". So, we tell it.
