Merge tag 'drm-msm-next-2023-10-17' of https://gitlab.freedesktop.org/drm/msm into drm-next

Updates for v6.7

DP:
- use existing helpers for DPCD handling instead of open-coded functions
- set the subconnector type according to the plugged cable / dongle
  skip validity check for DP CTS EDID checksum

DPU:
- continued migration of feature flags to use core revision checks
- reworked interrupts code to use '0' as NO_IRQ, removed raw IRQ indices
  from log / trace output

gpu:
- a7xx support (a730, a740)
- fixes and additional speedbins for a635, a643

core:
- decouple msm_drv from kms to more cleanly support headless devices (like
  imx5+a2xx)
