qcacmn: Add support to configure MSDU max aggregation limit
Currently FISA max msdu aggregation limit is fixed and always
programmed as 0xf, but there are platforms which support different
aggregation limit. So add support to configure different aggregation
limits while sending HTT FISA config message to F.W.
