[U-Boot] [PATCH 2/6] net: sun8i-emac: use new, generic GPIO setup routine

[Andre Przywara <andre.przywara@arm.com>]

Instead of open-coding the fairly generic pinmux setup in the sun8i-emac
driver, let's just use the new common implementation of that.
This has also the advantage of supporting the newpinctrl bindings, so
the driver can cope with the upstream Linux DTs.
