This series is a split out of version 4 - Raspberry PI 4 V3D enablement send
by Peter Robinson [1]. It attempts to enable BCM2711 V3D support for the
power management driver. It's a rework of the less controversial changes
(excluding V3D GPU driver changes) so this can be reviewed and applied faster.

Changes in V4:
- refactor bcm2835_pm_get_pdata to be easier to read
- remove DT runtime checks and rely on DT schema as suggested by Lee
- fix comment style as found by Lee

Changes in V3:
- add more Reviewed-by by Peter
- fix minItems in Patch #3 found by Rob

Changes in V2:
- add Peter's Reviewed-by
- simplify schema for rpivid_asb as suggested by Rob
- fix reference and clarify fallback & error handling in patch #7
- drop unnecessary newline in patch #9
- improve log messages as noticed by Peter

Changes since the mention series:
- fix DT schema errors
- make rpivid_asb register optional in DT schema
- avoid code duplication in BCM2835 ASB enable/disable
- rework ASB V3D handling so we don't need the V3D flag
- avoid log errors for optional register
- use a define for expected ASB_AXI_BRDG_ID result
- fix copy & paste issues in bcm2835-pm changes
