soc/ti/am335x: Add SDRAM initialization driver

Adds code taken and (barely) adapted from U-Boot (release 2020.04,
commit 36fec02b1f90b92cf51ec531564f9284eae27ab4) for SDRAM initialization.
This should in theory work for other configurations than the Beaglebone
Black's DRAM configuration, but hasn't been tested.
