The current algorithm to bring additional BIG CPUs is very
conservative. It works when BIG tasks alone run on BIG
cluster. When co-location and scheduler boost features
are activated, small/medium tasks also run on BIG cluster.
We don't want these tasks to downmigrate, when BIG CPUs are
available but isolated. The following changes are done to
un-isolate CPUs more aggressively.
(1) Round up the big_avg. When the big_avg indicates that
there are 1.5 tasks on an average in the last window, it
indicates that we need 2 BIG CPUs not 1 BIG CPU.
(2) Track the maximum number of running tasks in the last
window on all CPUs. If any of the CPU in a cluster has more
than 4 runnable tasks in the last window, bring an additional
CPU to help out.

When a short sleeping task goes for a long sleep, the task's
avg_sleep_time signal gets boosted. This signal will not go
below short_sleep threshold for a long time time even when the
task run in short bursts. This results in frequent preemption
of other tasks as the short burst tasks are placed on busy CPUs.
The idea behind tracking avg_sleep_time signal is to detect if a
task is short sleeping or not. Limit the sleep time to twice the
short sleep threshold to make avg_sleep_time signal more responsive.
This won't affect regular long sleeping tasks, as the avg_sleep_time
would be higher than threshold.

Get_Source_Cap message is responded by sending source capability message
without running sender response timer after GoodCRC is received. As a
result if sender response is timed out driver is not issuing hard reset.
Fix the issue by moving policy engine state from PE_SRC_READY to
PE_SRC_SEND_CAPABILITIES which starts sender response timer and handles
timeout.

Extcon is required by the USB controller to switch between
host and peripheral modes using BSV and ID events. If the
DT node of a particular controller does not have 'extcon'
property set but the mode is set to host only using
dr_mode = "host", then we do not fail the probe and
bring up the controller in host mode.
Add another case to the probe that when extcon prop is not
set and the controller mode is set to DRD, then bring up
the device in host mode. User can always change the mode
using sysfs.
