Subject: [PATCH 4.7 115/184] pinctrl: sunxi: fix uart1 CTS/RTS pins at PG on A23/A33

4.7-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Icenowy Zheng <icenowy@...c.xyz>

commit 486095fae3a8a6b1ae07c51844699d9bd5cfbebc upstream.

PG8, PG9 is said to be the CTS/RTS pins for UART1 according to the A23/33
datasheets. However, the function is wrongly named "uart2" in the pinctrl
driver. This patch fixes this by modifying them to be named "uart1".
