Currently u-boot running on mt7622 will print an warning log at beginning:
serial_mtk serial@11002000: pinctrl_select_state_full: uclass_get_device_by_phandle_id: err=-19
It turns out that the pinctrl uclass can't work properly in board_f stage.
Since the uart0 is the default UART device used by bootrom, and will be initialized in both bootrom and tf-a bl2. It's ok not to setup pinctrl for uart0 in u-boot.
This patch removes the default pinctrl of uart0 to suppress the unwanted warning.

Applied to u-boot/master, thanks!
