generic: 5.15: backport support for Marvell 88E6361 switch
New revision of Methode eDPU boards uses Marvell 88E6361 switch, so lets
backport it from kernel 6.5.

Since 5.15 doesnt have phylink_get_caps I had to modify the backport to
use the old mv88e6393x_phylink_validate instead.
I had to fixup one more instance of port_max_speed_mode as well that is not
present in 6.5.
