Add support to find relocated payload base address
OPAL relocates itself after boot. During MPIPL, hostboot needs to access
relocated SPIRAH. Hence lets add support to get relocated payload base address.
OPAL will use SBE stash chip-op to send relocated address to SBE. During early
IPL SBE sends stashed data to hostboot. And hostboot will use that information
to find relocated payload (OPAL) base.
SBE stash chip op:
key = 0x03
val = <relocated payload base address>
