By default slow it down as auto margins can lead to faster ramping up in
low activity use cases.
Set it back to default in GAME mode to retain previous behavior. Set it
explicitly for DISPLAY_IDLE as a potential area for more tuning in the
future.

And reduce DownRateLimitUs to 500us as the system should be more
reactive now when something needs to rampup quickly.
Enable pertask iowait boost too as with auto dvfs headroom enabled all
tasks will start form 0 util_avg and this could impact iowait tasks
without this being enabled to help them migrate up to bigger cores.
Camera use cases should still use their own default DownRateLimitUs and
disable this feature to keep their dvfs_headroom tuning intact.

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.
