sfc: extend NVRAM MCDI handlers

Browse source

Support variable write-alignment, and background updates.  The latter
 allows other MCDI to continue while the device is processing an
 MC_CMD_NVRAM_UPDATE_FINISH, since this can take a long time owing to
 e.g. cryptographic signature verification.
Expose these handlers in mcdi.h, and build them even when
 CONFIG_SFC_MTD=n, so they can be used for devlink flash in a
 subsequent patch.
