Subject: [PATCH v2 5/8] riscv: dts: thead: Adjust TH1520 GPIO labels
From: Emil Renner Berthing <emil.renner.berthing@...onical.com>
Adjust labels for the TH1520 GPIO controllers such that GPIOs can be
referenced by the names used by the documentation. Eg.
GPIO0_X -> <&gpio0 X Y>
GPIO1_X -> <&gpio1 X Y>
GPIO2_X -> <&gpio2 X Y>
GPIO3_X -> <&gpio3 X Y>
GPIO4_X -> <&gpio4 X Y>
AOGPIO_X -> <&aogpio X Y>
Remove labels for the parent GPIO devices that shouldn't need to be
referenced.
