[PATCH 2/2] arm64: zynqmp: Enable TI phy reset via GPIO

From: Harini Katakam <harini.katakam at amd.com>

Add DT property to support reset of TI PHY connected to GEM.
This is present in RevA DT but needs to be extended RevB/1.0/1.1
versions which are built on top.

Fixes: 2b1db7b18c97 ("arm64: zynqmp: Wire GEM reset gpio")
