sfc: add missing NVRAM partition types for EF10
Expose the MUM/SUC Firmware, UEFI Expansion ROM and MC Status partitions
of the NIC's NVRAM as MTDs if found on the NIC. The first two are needed
in order to properly update them when performing firmware updates; the MC
Status partition is used to determine whether a signed firmware image was
accepted or rejected by a Secure NIC.
