common/sfc_efx/base: support MAC address edit actions in MAE

In a tunnel packet, these actions affect the inner header if
action DECAP is set; otherwise, they affect the outer header.

Adding these actions is done in two steps: add the action to
the action mask and indicate the MAC address entry ID to use.
This allows the user to check the order of actions first and
allocate resources when time comes to enable the action rule.

common/sfc_efx/base: support NIC DMA memory regions API

NIC DMA memory regions API allows to establish mapping of DMA addresses
used by NIC to host IOVA understood by the host when IOMMU is absent
and NIC cannot address entire host IOVA space because of too small
DMA mask.

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.
