Subject: [PATCH] pinctrl: Ingenic: Add missing UART2 group C for X1000/E

X1000/E has a third UART2 pin group selection, which uses the TDI(G2) as RX
and TDO(G1) as TX. This configuration is becoming increasingly popular in
newer core boards, such as the Halley2 v4.1. This is done by enabling
function 1 of a "virtual pin" PC31. See section 19.3.3 of the X1000
Programming Manual for details.
