FSP: Pass FSP image base address to find_fsp
Add a parameter to find_fsp which is the image base address. Adjust the
fake stack in cache_as_ram.inc to pass in the read-only FSP image base
address. In fsp_notify, pass in the read-only FSP image base address
when the FSP header pointer is NULL. In find_fsp, validate the FSP
binary image starting from the specified image base address.
BRANCH=none
BUG=None
TEST=Build and run on Skylake
