The actual RAM timings in the phyFLEX BSP are generated for 528 MHz RAM clock
frequency, but the i.MX 6Solo/DualLite has only a 400 MHz RAM clock. These new
timings are accompanied by a speed increase of approx 10%.

The main idea behind this patch is to avoid redundant code.  Because of
the module similarities of all i.MX6 based phytec boards, we can merge
its code.

The phytec-som-imx6 merges the code of all i.MX6 based phytec SOMs.  So
we will have only one "board" in the barebox for phyCARD-i.MX6 and
phyFLEX-i.MX6.
