msm-next for v6.3

There is one devfreq patch, maintainer acked to land via msm-next to
avoid a build break on platforms that do not support PM_DEVFREQ.  And
otherwise the usual assortment:

GPU:
- Add MSM_SUBMIT_BO_NO_IMPLICIT
- a2xx: Support to load legacy firmware
- a6xx: GPU devcore dump updates for a650/a660
- GPU devfreq tuning and fixes

DPU, DSI, MDSS:
- Support for SM8350, SM8450 SM8550 and SC8280XP platform

Core:
- Added bindings for SM8150 (driver support already present)

DPU:
- Partial support for DSC on SM8150 and SM8250
- Fixed color transformation matrix being lost on suspend/resume
- Include DSC blocks into register snapshot
- Misc HW catalog fixes

DP:
- Support for DP on SDM845 and SC8280XP platforms
- HPD fixes
- Support for limiting DP link rate via DT property, this enables
- Support for HBR3 rates.

DSI:
- Validate display modes according to the DSI OPP table
- DSI PHY support for the SM6375 platform
- Fixed byte intf clock selection for 14nm PHYs
- Fix the case of empty OPP tables (fixing db410c)
- DT schema rework and fixes

HDMI:
- Turn 8960 HDMI PHY into clock provider,
- Make 8960 HDMI PHY use PXO clock from DT

MDP5:
- Schema conversion to YAML
