common/intel/cse: Add function to perform CSE FW update in ramstage
When compressed ME RW blobs are used for CSE FW update, it has to be
loaded into memory to decompress. So perform CSE FW update in ramstage.
Alder Lake-N based nissa boards use compressed ME RW blobs to save on
SPI flash size. Enable CSE FW update in ramstage.
BRANCH=firmware-brya-14505.B
TEST=Perform CSE FW update on nivviks and verify upgrade/downgrade
works.
