Subject: [PATCH 0/2] net: stmmac: dwmac-rk: Validate rockchip,grf and php-grf during probe

All Rockchip GMAC variants require writing to GRF to configure e.g.
interface mode and MAC rx/tx delay. The GRF syscon regmap is located
with help of a rockchip,grf and rockchip,php-grf phandle.

However, validating the rockchip,grf and rockchip,php-grf syscon regmap
is deferred until e.g. interface mode or speed is configured.

This series change to validate the rockchip,grf and rockchip,php-grf
syscon regmap at probe time to help simplify the SoC specific operations.

I do not expect that this will introduce any regression. Prior to this,
use of a device tree without a rockchip,grf would fail when interface
mode or speed is configured, with this use of such device tree would
instead result in failure at probe time.
