rockchip: ns16550: dm: convert fdt_get to dev_read

Browse source 
With the new dev_read functions available, we can convert the rockchip
architecture-specific drivers and common drivers used by these devices
over to the dev_read family of calls.

This covers the serial driver (ns16550 and compatible) used for the
Rockchip devices.
