Felix Held d1d6479ddf soc/amd/stoneyridge/mca: implement and use mca_has_expected_bank_count
This aligns the mca_check_all_banks implementation in the common mca.c
with the one in the common mcax.c file. Do the MCA bank count check
before the !is_warm_reset() check, so that a mismatch also gets printed
on the cold boot path.
