This change is specific to 8952, 8956 and 8976 targets.
This is to reduce CPU scaling in encoding case.

1.Changes to set CPU0 min freq for 8952 target as below:.
Display off case : set to 499.2Mhz
Display on case : set to 960Mhz.
2.Changes to set CPU0 and CPU4 interactive timer rate values
Display off cases : Set cpu0 and cpu4 to 50ms.

Previously the enums to limit the maximum number
of cores online were using the same resource as
minimum number of cores. Separate the min and max
to each have their own resource.

Currently power HAL sets display off hint to 500ms for
Interactive Governor, this change modifies the hint to 50ms
to enable CPU to sample and scale better.

If the interactive governor is being used, vote to turn off
io_is_busy when video encode starts to reduce power consumption.

Add and use the opcode to disable synchronization
of cores on foreground thread migration.
Synchronization of cores on foreground thread migration
feature is on by default so we will disable
when the display is off and encode/decode hints.

Change needed during display off use cases to improve
power with specific hints to enable power collapse and
set sync/optimal frequency to 650 Mhz

Display off opcode used to inform PerfLock the display is off.
Power collapse enable opcode allows users to enable power collapse
modes on all cpus.

When the display turns off, the MSM8974
needs to set ondemand governor's sync_freq
and optimal_freq parameters to values different
from other targets. To accomplish this, override
the handling for set_interactive. Also refactor
power HAL to remove unnecessary macros.
Change-Id: I009ee88886abfb4f8423de3b2d85549fd0e65205
Process video decode hints and display-off hints
in the power HAL. Also move to using the perflock
API to request system-level parameter changes.
