feature behind a power boost profile which can only be triggered from
camera hal and is controlled by a mendel flag.

Since the system is more reactive now when tasks are getting busier, set
DownRateLimitUs to 500us to avoid increasing power.
Also enable pertask iowait boost as util_avg will always start from
0 for forked tasks and this could impact io tasks that need additional
help to ensure to migrate to bigger core if they need more perf.

UClamp.min of all threads in top app is set to mid core max capacity during photo capture, which will dispatch them to big core.
Critical threads of photo capture will be interrupted due to their lower priority, while other cores idle.
To deal with this situation,
prefer_idle mask to big/mid cores can reduce the idle in mid cores.
UClamp.min on nice can set UClamp.min of photo capture critical threads to mid core max capacity, while others as zero,
this can make critical threads run on big core without frequently interrupted.
By applying this, photo capture latency can be reduced with slight change of power consumption.

use-cases once RT threads are enabled. Even without the RT patch
(ag/27725456), we can see savings without any impact to framedrop rate.

pa/2830448 removes the core ignorance logic in PMU and causes the
behavior of PMU to change. With the new PMU logic, we need to re-tune
all the SPC thresholds for camera use-cases. This CL adjusts SPC
thresholds accordingly, so that we do not have power regression once the
PMU change in the kernel is merged.
