soc/intel/common/cse: Add helper API for CSE SPI Protection Mode

This patch checks if CSE's spi protection mode is protected or
unprotected. Returns true if CSE's spi protection mode is protected,
otherwise false.

BUG=b:211954778
TEST=Able to build and boot brya with this change. Calling
`cse_is_hfs1_spi_protected()` in coreboot is able to provide
the SPI protection status.
