[PATCH v2 20/35] rockchip: Add a VPL image

[Simon Glass]

The VPL image is immutable and has a single VPL binary plus a devicetree
for each board we need to support.

The devicetree is run through fdtgrep to remove unwanted nodes and
properties and reduce its size.

Changes in v2:
- Move VPL things into a separate file
