From: Michael Riesch <[email protected]>
We've so far relied on GPIO controllers being named "gpioX", while the
binding mandates gpio controllers being just called "gpio". This already
broke rk3288 support and rk3568.dtsi upstream also differs from the
version in barebox' arch/arm/dts in that regard.
Instead, do like Linux does and use the alias to match the controllers to
the GPIO banks with a fallback to probe order.
Fixes: 3f2f5980d517 ("dts: update to v5.16-rc1")
