This patch series enables support for MSM8956/76 and its Adreno 510
GPU on the current DRM driver.

The personal aim is to upstream MSM8956 as much as possible.

This code has been tested on two Sony phones featuring the Qualcomm
MSM8956 SoC.

Changes in v2:
- MDP5: Documented tbu and tbu_rt clocks (Jeffrey)
- Adreno510:
  - Lower case hex where required (Jordan)
  - Direct register writes (Jordan)
  - Used gpu_rmw() where required (Jordan)
  - No mentioning of unsupported A5xx (Jordan)
  - ZAP firmware exclusions not per-model (Rob)

Changes in v3:
- Rebased onto linux-next 20191015
- Renamed MSM8x56 references to MSM8x76 (the reason is that I am
  using the 8976/8x76 name for all the other drivers. Also, the
  8976 and 8956 chips are equal and the only changing part is
  the CPU big cores count)
- Splitted dt-bindings modifications as per request (Sean)

Changes in v4:
- Fixed io_start for the secondary dsi phy on family-b
