arm64: dts: rockchip: add gpio-line-names to radxa-zero-3

Browse Source 
Add names to the pins of the general-purpose expansion header as given
in the Radxa documentation[1] following the conventions in the kernel[2]
to make it easier for users to correlate pins with functions when using
utilities such as 'gpioinfo'.
