ARM: DTS: Update pcm052 based dts files (bk4r1/pcm052)

This commit provides update and renames the bk4r1.dts to vf610-bk4r1.dts
file with more on SoC HW description.
The pcm052.dts has been renamed to vf610-pcm052.dts as well.

Moreover, a new vf610-pcm052.drsi file has been introduced
to reuse the common code between devices based on Phytec's
pcm052 modules.
Ported from Linux kernel - v4.20 (tag)
