The source PLL to be used by each DSI PHY should be decided by
DSI manager based on dual DSI information, while the register
programming to select PLL is different from one type of PHY to
another. This change adds the H/W difference to PHY configuration
and updates the interface between DSI manager and PHY.
With this change, PLL selection can be supported on different
targets.

There are different types of PHY from one chipset to another, while
the DSI host controller is relatively consistent across platforms.
Also, the PLL inside PHY is providing the source of DSI byte and
pixel clocks, which are used by DSI host controller. Separated devices
for clock provider and clock consumer make DSI driver better fit into
common clock framework.

DSI byte clock and pixel clocks are sourced from DSI PLL.
This change adds the DSI PLL source clock driver under
common clock framework.
This change handles DSI 28nm PLL only.

This change adds the DSI connector support in msm drm driver.
v1: Initial change
v2:
- Address comments from Archit + minor clean-ups
- Rebase to not depend on msm_drm_sub_dev change [Rob's comment]
v3: Fix issues when initialization is failed
