Subject: [PATCH] arm: dts: hi3518ev20x: enable uart1 so boards can mux it for
 PTZ

A Baolian hi3518ev200 camera drives its pan/tilt mount over RS-485 on UART1
(OpenIPC/firmware#2675). With uart1 disabled there is no /dev/ttyAMA1 to send
on, whatever the board does with its pads.

The serial1 alias is already in this file. No pinmux: a board that leaves
its pads alone sees no change on the wire and only gains a tty node.
