drivers/spi: Add controller protection type
Some SPI controllers support both READ and WRITE protection
add a variable to the protect API for the callers to specify
the kind of protection they want (Read/Write/Both).
Also, update the callers and protect API implementation.
BUG=None
BRANCH=None
TEST=test that the mrc cache is protected as expected on soraka.
Also tried if the read protection is applied correctly.
