[U-Boot] [PATCH 7/7] rockchip: dm: convert fdt_get to dev_read

[Philipp Tomsich]

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 DRAM controller initialisation for the RK3188, RK3288
and RK3399... all of these read some of the tuning/setup/timing
parameters from the device-tree.
