Subject: [PATCH v4 0/5] Fix the parse_dt of exynos dsi and remove the OF graph

Hi All,

The dsi + panel is a parental relationship, so OF grpah is not needed.
Therefore, the current dsi_parse_dt function will throw an error,
because there is no linked OF graph for case such as fimd + dsi +
panel.

So the 1/5 patch parse the Pll, burst and esc clock frequency
properties in dsi_parse_dt and modified to create a bridge_node only
if there is an OF graph associated with dsi.

Also fixed the dts, which depend on the 1/5 patch. So removed the
ports node and move burst and esc clock frequency properties to the
parent (DSI node).

Changes for V4:
- Squashed patch 2, 3 and 4.
- Added Reviewed-by: Andrzej Hajda <a.hajda@...sung.com> on all patches.

Changes for V3:
- Split the patches considering the bisectability problem.

Changes for V2:
- Added the clear explanation for commit. (1/5 patch)
- Fixed it to the same subject as the actual work. (2/5 ~ 5/5 patches)

Best Regards,
Hoegeun
