AFAICS in linux-firmware we don't have any 70.5.4 binaries, the newest
ones are 70.5.1.

Some of the info here is redundant from print_fw_ver(). Can we have a
single print with all the info we need?
Something like:
GuC firmware i915/mtl_guc_70.bin (v70.6.5, expected v70.6.4 or newer)
Otherwise, I'd suggest demoting this to gt_dbg to avoid printing the
same thing twice at info verbosity
