[PATCH AUTOSEL 5.4 18/26] dts: phy: add GPIO number and active state used for phy reset

From: Sagar Shrikant Kadam sagar.kadam@sifive.com

[ Upstream commit a0fa9d727043da2238432471e85de0bdb8a8df65 ]

The GEMGXL_RST line on HiFive Unleashed is pulled low and is using GPIO number 12. Add these reset-gpio details to dt-node using which the linux phylib can reset the phy.
