====================
allwinner: a523: Rename emac0 to gmac0

This small series aims to align the name of the first ethernet
controller found on the Allwinner A523 SoC family with the name
found in the datasheets. It renames the compatible string and
any other references from "emac0" to "gmac0".

When support of the hardware was introduced, the name chosen was
"EMAC", which followed previous generations. However the datasheets
use the name "GMAC" instead, likely because there is another "GMAC"
based on a newer DWMAC IP.
