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

[Peng Fan]

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