Subject: [PATCH net 2/2] arm64: dts: allwinner: a523: Rename emac0 to gmac0

From: Chen-Yu Tsai <wens@...e.org>

The datasheets refer to the first Ethernet controller as GMAC0, not
EMAC0.

Fix the compatible string, node label and pinmux function name to match
what the datasheets use. A change to the device tree binding is sent
separately.

Fixes: 56766ca6c4f6 ("arm64: dts: allwinner: a523: Add EMAC0 ethernet MAC")
Fixes: acca163f3f51 ("arm64: dts: allwinner: a527: add EMAC0 to Radxa A5E board")
Fixes: c6800f15998b ("arm64: dts: allwinner: t527: add EMAC0 to Avaota-A1 board")
