Merge series "ASoC: Intel: catpt: Offload fixes and code optimization" from Cezary Rojewski <cezary.rojewski@intel.com>:

First two of the series address bugs connected mainly to offload streams:
- scenarios with very low buffer sizes: RESET_STREAM IPC timeouts
- fix lp clock selection when switching between PAUSE <-> RESUME states:
  glitches on first offload when no additional stream is opened
  simultaneously

Follow ups are: code reduction and optimization oriented patches.
This has been foretold in:

[PATCH v10 00/14] ASoC: Intel: Catpt - Lynx and Wildcat point
https://www.spinics.net/lists/alsa-devel/msg116440.html
  Note: LPT power up/down sequences might get aligned with WPT once
  enough testing is done as capabilities are shared for both DSPs.

First, optimize applying of user settings - prevent redundand calls from
happening - and then as mentioned above, streamline power on/off sequence
for LPT and WPT.

Cezary Rojewski (5):
  ASoC: Intel: catpt: Skip position update for unprepared streams
  ASoC: Intel: catpt: Correct clock selection for dai trigger
  ASoC: Intel: catpt: Optimize applying user settings
  ASoC: Intel: catpt: Streamline power routines across LPT and WPT
  ASoC: Intel: catpt: Cleanup after power routines streamlining
