common/sfc_efx/base: support to configure MAC to keep FCS

Drivers cannot determine if received packet includes the FCS or not.
Only packets with an external port have the FCS included and functions
without link control privilege cannot determine the MAC configuration.

This patch is trying to make assumptions that: if PF is the only
function (there are no VFs or additional PFs); it can set the MAC
configuration and it never expects packets it sends to be looped back
then it can assume that changed the MAC configuration to include the FCS
is safe and that all received packets will include their FCS.

NIC DMA memory regions API allows to establish mapping of DMA addresses

The API does not allow to address entire host IOVA space, but allows
arbitrary regions of the space really used for the NIC DMA.

A DMA region needs to be mapped in order to perform MCDI initialization.
Since the NIC has not been probed at that point, its configuration cannot
be accessed and there an UNKNOWN mapping type is assumed.
