arm64: dts: rockchip: fix pinmux of UART0 for PX30 Ringneck on Haikou

Browse Source 
commit 2db7d29c7b upstream.

UART0 pinmux by default configures GPIO0_B5 in its UART RTS function for
UART0. However, by default on Haikou, it is used as GPIO as UART RTS for
UART5.

Therefore, let's update UART0 pinmux to not configure the pin in that
mode, a later commit will make UART5 request the GPIO pinmux.
