[PATCH v2 0/5] IO and fast wake lines calculation and increase fw sync length

[Jouni Högander]

This patch set is improving IO and fast wake lines calculation in PSR
code:

Use actual fast wake sync pulse count in calculation
Implement getter for IO buffer wake times and use that.
Better presentation on how these are calculated.
Use calculation for display version < 12 as well.

Also number of precharge pulses is increased by 2 pulses to fix
problems with certain panel models.

v2:
  - do not add function pointer
  - rename io_wake_time in if block to io_buffer_wake_time
  - rename get_io_wake_time to get_io_buffer_wake_time
  - use calculation for display version < 12 as well
  - split LunarLake IO buffer wake times as a separate patch
