sfc: Extend MTD driver for use with new NICs
In new NICs flash is managed by firmware and we will use high-level
operations on partitions rather than direct SPI commands. Add support
for multiple MTD partitions per flash device and remove the direct
link between MTD and SPI devices. Maintain a list of MTD partitions
in struct efx_nic.
