rockchip: xhci: 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 change covers the USB3 (xhci) driver for the Rockchip devices.
