[v3,00/19] Venus cleanups

Message

With the driver supporting multiple generations of hardware, some mold
has definitely grown over the code..

This series attempts to amend this situation a bit by commonizing some
code paths and fixing some bugs while at it.

Only tested on SM8250.

Definitely needs testing on:

- SDM845 with old bindings
- SDM845 with new bindings or 7180
- MSM8916
- MSM8996

Changes in v3:
- Drop const within const patch
- Pick up tags
- Some stylistic fixes in kerneldoc
- Link to v2: https://lore.kernel.org/r/[e-mail]

Changes in v2:
- Fix "set but unused" warning in "Drop cache properties in resource struct"
- Fix modular build with "Commonize vdec_get()"
- Rebase
- Test again on 8250, since nobody else tested other platforms since the last
  submission (or at least hasn't reported that), I'm assuming nobody cares
- Needs to be tested atop [1] and similar, it's in latest -next already
- Link to v1: https://lore.kernel.org/r/[e-mail]
