soc/amd/picasso: implement and use mca_is_valid_bank
In mca_check_all_banks only check valid MCA banks for errors. This
aligns the Picasso code a bit more with the Stoneyridge code base which
will be updated in a follow-up patch. This is a preparation for
commonizing the MCA(X) handing in the soc/amd sub-tree.
