MTL introduces a new way to instruct the PUnit with
power and bandwidth requirements of DE. Add the functionality
to program the registers and handle waits using interrupts.
The current wait time for timeouts is programmed for 10 msecs to
factor in the worst case scenarios. Changes made to use REG_BIT
for a register that we touched(GEN8_DE_MISC_IER _MMIO).
Wa_14016740474 is added which applies to Xe_LPD+ display
v2: checkpatch warning fixes, simplify program pmdemand part
v3: update to dbufs and pipes values to pmdemand register(stan)
Removed the macro usage in update_pmdemand_values()
v4: move the pmdemand_pre_plane_update before cdclk update
pmdemand_needs_update included cdclk params comparisons
pmdemand_state NULL check (Gustavo)
pmdemand.o in sorted order in the makefile (Jani)
update pmdemand misc irq handler loop (Gustavo)
active phys bitmask and programming correction (Gustavo)
v5: simplify pmdemand_state structure
simplify methods to find active phys and max port clock
Timeout in case of previou pmdemand task pending (Gustavo)
v6: rebasing
updates to max_ddiclk calculations (Gustavo)
updates to active_phys count method (Gustavo)
v7: use two separate loop to iterate throug old and new
crtc states to calculate the active phys (Gustavo)
v8: use uniform function names (Gustavo)
v9: For phys change iterate through connectors (Imre)
Look for change in phys for pmdemand update (Gustavo, Imre)
Some more stlying changes (Imre)
Update pmdemand state during HW readout/sanitize (Imre)
v10: Fix CI checkpatch warnings
v11: use correct pmdemand object pointer during hw readout,
simplify the check for phys need update (Gustavo)
v12: Handle possible non serialize cases (Imre)
Initialise also pmdemand params HW readout (Imre)
Update active phys mask during sanitize calls (Imre)
Check TC/encoder changes to limit connector update (Imre)
v13: Check display version before accessing pmdemand functions
v14: Move is_serialized to intel_global_state.c
simplify update params and other stlying issues (Imre)
