Add the needed DP PLL specific files to support
display port interface on msm targets.
The DP driver calls the DP PLL driver registration.
The DP driver sets the link and pixel clock sources.

Add display port support in DPU by creating hooks
for DP encoder enumeration and encoder mode
initialization.
changes in v2:
- rebase on [2] (Sean Paul)
- remove unwanted error checks and
switch cases (Jordan Crouse)

The Documentation/DMA-API-HOWTO.txt states that the dma_map_sg() function
returns the number of the created entries in the DMA address space.
However the subsequent calls to the dma_sync_sg_for_{device,cpu}() and
dma_unmap_sg must be called with the original number of the entries
passed to the
This change adds support to scale src clk and bandwidth as
per composition requirements.
Interconnect registration for bw has been moved to mdp
device node from mdss to facilitate the scaling.

"The PM core always increments the runtime usage counter
before calling the ->suspend() callback and decrements it
after calling the ->resume() callback"
DPU and DSI are managed as runtime devices. When
suspend is triggered, PM core adds a refcount on all the
devices and calls device suspend,
