drm/meson: add mode selection limits against specific SoC revisions
The Amlogic S805X/Y uses the same die as the S905X, but with more
limited graphics capabilities.
This adds a soc version detection adding specific limitations on the HDMI
mode selections.
Here, we limit to HDMI 1.2a max HDMI PHY clock frequency.
Changes sinces v1:
- Moved frequency check in the vclk code, and also checks DMT modes
