Add the driver for the Airoha EN8811H 2.5 Gigabit PHY. The PHY supports
100/1000/2500 Mbps with auto negotiation only.
The driver uses two firmware files, for which updated versions are added to
linux-firmware already.
Based on the Linux upstream 8811 driver code(air_en8811h.c),
I have modified the relevant process to align with the U-Boot boot sequence.
and have validated this on Banana Pi BPI-R3 Mini.
The MD32 FW is currently stored in eMMC partition 1 on Banana Pi BPI-R3 Mini,
and it is loaded from there.
If this is ported from Linux, please include Linux commit SHA from which
this is ported.

Can this do the same thing as Aquatia PHY and load the PHY firmware from
filesystem on block device instead , using the blk* or fs* commands ?
Then the hard-coded filesize and co. won't be necessary.
If you need board specific loading override, implement __weak default
loading from file on filesystem by default (see what Aquatia does) and
then override the loading function on board or architecture level.
U-Boot really needs a proper generic firmware loader, because this
firmware stuff keeps showing up more and more, but I cannot ask you to
write one only because of this PHY ... but if you are up for a challenge ...
