drivers/tpm/cr50: Use cr50_get_firmware_version in get_board_cfg

cr50_get_board_cfg() may be called in ramstage for some mainboards in
order to determine the BOARD_CFG register's value. The code was
written assuming that the firmware version was already retrieved, but
for boards calling this in ramstage, this is not the case. Therefore,
instead of using the cached cr50_firmware_version (which is all 0s in
ramstage at that time), use the cr50_get_firmware_version function
instead.

BUG=b:225206079, b:220685274
TEST=boot on brya0 and see:

[INFO ]  Enabling GPIO PM b/c CR50 has long IRQ pulse support
in the logs.
