In H3, PA5 can be used as PWM and UART0. If the PWM is used, the console
UART should be moved to other port.
This patch enables UART1 pinctrl to support this case.

	PA5: PWM
	PG6, PG7: debug console

Our policy is that we don't introduce new pinctrl nodes that are not
used by any board to avoid bloating the DT too much with unused nodes.

If you have a board using it, please submit that change as well.

UART1 was already added in sun8i-h3.dtsi, so I drop this change in v2.
