====================
net: dsa: b53: mmap: Add bcm63268 GPHY power control

The gpio controller on the bcm63268 has a register for
controlling the gigabit phy power. These patches disable
low power mode when enabling the gphy port.

This is based on an earlier patch series here:
https://lore.kernel.org/20250306053105.41677-1-kylehendrydev@gmail.com

I have created a new series since many of the changes
were included in the ephy control patches:
