Another round of these patches. Only change this time is the addition
of a patch to limit the resolutions to the ones supported by the VOP
driver which should resolve the regression reported by FUKAUMI Naoki.


Changes since v3:
- Add patch to limit VOP resolutions to hardware capabilities

Changes since v2:
- Use correct register values for mpll_cfg
- Add patch to discard modes we cannot achieve

Changes since v1:
- Allow non standard clock rates only on Synopsys phy as suggested by
  Robin Murphy
