mb/google/zork: Remove validity checks for FW_CONFIG in CBI

After confirming that all zork variants and phases have valid
FW_CONFIG value in CBI, this patch is dropping FW_CONFIG validity checks
like VARIANT_HAS_FW_CONFIG and VARIANT_BOARD_VER_FW_CONFIG_VALID in Kconfig
and will also remove associated helper functions.

BRANCH=none
BUG=b:162344105,b:152817444
TEST=Check if FW_CONFIG bits can be read in coreboot and FW_CONIFG helper
     function do not return 0 if board has a valid FW_CONFIG in CBI.
