rockchip: spi: dm: convert fdt_get to dev_read

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 rk_spi.c (SPI driver) used in Rockchip devices.
