Subject: [PATCH v2 0/4] clk: meson: Add video clocks path

This patchset is an attempt to handle the Amlogic Meson GX Video clock
in the Common Clock Framework in order to move the video pipeline and
HDMI controller clock management out of the Meson DRM Driver.

In order :
- Add support the VID_PLL fully programmable divider used right after the
  HDMI PLL clock source.
- Fix the GXL HDMI PLL DCO
- Add the video clock bindings covering all the video graphics pipeline
  and the HDMI controller.
- Add the clocks entries used in the video clock path

The vid_pll programmable divider is introduced in its R/O form right now,
but will be extended to be R/W in a next iteration.

All dividers are flagged with CLK_GET_RATE_NOCACHE, and all gates are flagged
with CLK_IGNORE_UNUSED since they are currently directly handled by the
Meson DRM Driver.

Once the DRM Driver is fully migrated to using the Common Clock Framework
to handle the video clock tree, the CLK_GET_RATE_NOCACHE and CLK_IGNORE_UNUSED
will be dropped.

Changes since v1 at [1]:
 - Fixed comments from Martin
 - Fixed GXL HDMI PLL DCO
 - Added the missing HDMI controller clock
 - Moved bindings to a separate patch
 - Updated the commit logs
