msm: pm: Rearchitect power management code
The existing PM code relies on a levels table to determine the various
sleep modes including the system sleep states. Splitting them into cpu
and system/cluster specific levels is a more appropriate representation
of the existing system. As a part of this rearchitecture, the decision
to enter a low power mode is made within lpm_levels module. Unlike
earlier, the decision was split between pm-8x60 and lpm_levels.
To this effect, the lpm_levels directly registers with the cpuidle
driver instead of relying on a glue msm-cpuidle driver. The
functionality of the cpuidle driver was limited to calling into a PM
driver and without providing any additional functionality.
While at it, also remove any references to unused enums and
functionality.
