[ Upstream commit fa8785e5931367e2b43f2c507f26bcf3e281c0ca ]

Change suniv f1c100s pinctrl,PD14 multiplexing function lvds1 to uart2

When the pin PD13 and PD14 is setting up to uart2 function in dts,
there's an error occurred:
1c20800.pinctrl: unsupported function uart2 on pin PD14

Because 'uart2' is not any one multiplexing option of PD14,
and pinctrl don't know how to configure it.

So change the pin PD14 lvds1 function to uart2.
