soc/intel/jasperlake: Add function to display ME firmware status info

Add function to display ME Host Firmware Status registers. Make use of
print_me_fw_version() from CSE lib to print ME firmware version information.

Add manufacturing mode field in HFSTS1 register for JSL in place of,
spi_protection_mode in TGL.

BUG=None
BRANCH=None
TEST=Build and boot jslrvp. In coreboot logs, ME info can be seen.
