[U-Boot] [U-Boot, v2, 1/4] rockchip: evb-rk3328: set uart2 io routing to M1

[Philipp Tomsich]

> In rk3328, some function pin may have more than one choice, and muxed
> with more than one IO, for example, the UART2 controller IO,
> TX and RX, have 3 choice(setting in com_iomux):
> - M0 which mux with GPIO1A0/GPIO1A1
> - M1 which mux with GPIO2A0/GPIO2A1
> - usb2phy which mux with USB2.0 DP/DM pin.
> 
> This suppose to be set in SPL, but the U-Boot is also design to co-work
> with Rockchip SPL(miniloader) which may not setting this config, let's set
> this config to make sure the UART2 TX/RX working in U-Boot.
