Merge branch 'net-lan966x-add-support-for-fdma'

Horatiu Vultur says:

====================
net: lan966x: Add support for FDMA

Currently when injecting or extracting a frame from CPU, the frame
is given to the HW each word at a time. There is another way to
inject/extract frames from CPU using FDMA(Frame Direct Memory Access).
In this way the entire frame is given to the HW. This improves both
RX and TX bitrate.
