[PATCH] board: gateworks venice: add support for GPY111 phy

[Tim Harvey <tharvey@gateworks.com>]

The TI DP83867 phy has been replaced with the MaxLinear GPY111 phy due
to part availability.

Add support for it by adding LED config and dt-prop based internal delay
config tx-delay/rx-delay per PHY ID.
