[v9,0/4] Make IPA use PM_EM

Message

This removes the IPA-specific energy model code in favor of PM_EM which
does the same thing in a generic way. For more details, please read the
cover letter of the v7:

https://lore.kernel.org/lkml/[e-mail]/

Changes in v9:
 - Rebased on 5.4-rc5 and fixed conflicts with pm_qos changes

Changes in v8:
 - Fixed checkpatch errors (Rui)

Changes in v7
 - Added patch 02/04 to fix the build error reported by the kbuild bot

Changes in v6
 - Added Daniel's and Viresh's Acked-by to all patches

Changes in v5:
 - Changed patch 02 to guard IPA-specific code in cpu_cooling.c with
   appropriate ifdefery (Daniel)
 - Rebased on 5.2-rc2

Changes in v4:
 - Added Viresh's Acked-by to all 3 patches
 - Improved commit message of patch 3/3 to explain how it has no
   functional impact on existing users (Eduardo)

Changes in v3:
 - Changed warning message for unordered tables to something more
   explicit (Viresh)
 - Changed WARN() into a pr_err() for consistency

Changes in v2:
 - Fixed patch 01/03 to actually enable CONFIG_ENERGY_MODEL
 - Added "depends on ENERGY_MODEL" to IPA (Daniel)
 - Added check to bail out if the freq table is unsorted (Viresh)

Quentin Perret (4):
  arm64: defconfig: Enable CONFIG_ENERGY_MODEL
  PM / EM: Declare EM data types unconditionally
  thermal: cpu_cooling: Make the power-related code depend on IPA
  thermal: cpu_cooling: Migrate to using the EM framework
