Some time ago we started the process of converting HW blocks to use
revision-based checks instead of having feature bits (which are easy to
miss or to set incorrectly). Then the process of such a conversion was
postponed. (Mostly) finish the conversion. The only blocks which still
have feature bits are SSPP, WB and VBIF. In the rare cases where
behaviour actually differs from platform to platform (or from block to
block) use unsigned long bitfields, they have simpler syntax to be
checked and don't involve test_bit() invocation.

Changes in v4:
- Rebased on top of linux-next
- Dropped three controversial patches, will be submitted separately
- Folded MIXER_SDM845_MASK into MIXER_MSM8998_MASK as they are equal
  now.
- Link to v3: https://lore.kernel.org/r/20250424-dpu-drop-features-v3-0-cdaca81d356f@oss.qualcomm.com

Changes in v3:
- Repost, fixing email/author issues caused by b4 / mailmap interaction
- Link to v2: https://lore.kernel.org/r/20250424-dpu-drop-features-v2-0-0a9a66a7b3a2@oss.qualcomm.com

Changes in v2:
- Rebased on top of the current msm-next
- Link to v1: https://lore.kernel.org/r/20241214-dpu-drop-features-v1-0-988f0662cb7e@linaro.org
