sfc: document devlink flash support 



Update the information in sfc's devlink documentation including
 support for firmware update with devlink flash.
Also update the help text for CONFIG_SFC_MTD, as it is no longer
 strictly required for firmware updates.

Flash Update

============



The ``sfc`` driver implements support for flash update using the

``devlink-flash`` interface. It supports updating the device flash using a

combined flash image ("bundle") that contains multiple components (on ef10,

typically ``fw.mgmt``, ``fw.app``, ``fw.exprom`` and ``fw.uefi``).



The driver does not support any overwrite mask flags.
