sfc: extend MTD support for newer hardware

Browse Source 
The X2 family of NICs (based on the SFC9250) have additional
MTD partitions for firmware and configuration. This includes
partitions that are read-only.

The NICs also have extended versions of the NVRAM interface,
allowing more detailed status information to be returned.
