net/sfc/base: define max desc number for every EF10 NIC For consistency with defines of min descriptor number, define max descriptor number for Huntington, Medford and Medford2.

net/sfc/base: support different event descriptor sizes For consistency with the size of Tx descriptors, the size of event descriptors should be a part of NIC config, not a macro that is common for all NIC families. Also, add a max number of EvQ buffers define which is needed to initialize an MCDI buffer at compile time.
