Bring back a set of patches extracted from [1] per Abhinav's suggestion.

Rework debugging overrides for the bandwidth and clock settings. Instead
of specifying the 'mode' and some values, allow one to set the affected
value directly.

Changes in v5:
- Fixed bps -> KBps in the comments (Abhinav)
- Split the core_clk_rate changes into a separate commit (Abhinav)
- Expanded commit message to note that debugfs bandwidth settings are
  not a subject to catalog thresholds (Abhinav)
- Temporarily dropped the patches actually reworking the debugfs modes,
  they will be reposted separately.
- Link to v4: https://lore.kernel.org/r/20250106-dpu-perf-rework-v4-0-00b248349476@linaro.org

Changes in v4:
- Dropped core_perf: from patch subject (Abhinav)
- Fixed indentation of _dpu_core_perf_crtc_update_bus() (Abhinav)
- Expanded commit messages to reflect different questions (Abhinav)
- Reworked existing files to specify max allowed average bandwidth
  (Abhinav)
- Fixed u32 vs u64 and KBps vs Bps values in debugfs interface
- Link to v3: https://lore.kernel.org/r/20240314-dpu-perf-rework-v3-0-79fa4e065574@linaro.org
