[PATCH] ARM: i.MX6: correct UART IOMUX_PADs

[PATCH] ARM: i.MX6: correct UART IOMUX_PADs

[Jonas Rebmann]

For SD3_DAT0, add the definition for UART1_RTS and correct UART1_CTS to
longer use the actual address of RTS Select Input Register.

As confirmed by the i.MX manual and dts/src/arm/nxp/imx/imx6q-pinfunc.h:

 #define MX6QDL_PAD_EIM_D19__UART1_CTS_B      0x09c 0x3b0 0x000 0x4 0x0
 #define MX6QDL_PAD_EIM_D19__UART1_RTS_B      0x09c 0x3b0 0x91c 0x4 0x0
