drivers/spi/tpm: Add support to cache the TPM firmware version

TPM firmware version is required for couple of use-cases during
ramstage - GPIO PM configuration for Intel SoCs, Board specific reset
when CSE Lite jumps from RO to RW. This change adds support to read the
TPM firmware version and cache it.

BUG=b:154333137, b:162290856
TEST=Ensure that the DUT boots to OS. Ensure that the firmware version
is cached and matches with the firmware version logged in the bootup
logs.
