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.
