Subject: pinctrl: sunxi: Fix A64 UART mux value

From: Andre Przywara <andre.przywara@arm.com>


[ Upstream commit 7c5c2c2d18d778e51fd8b899965097168306031c ]

To use pin PF4 as the RX signal of UART0, we have to write 0b011 into
the respective pin controller register.
Fix the wrong value we had in our table so far.
