Forcing a certain current limit is not supported in the current
driver, but well needed in when pd is active.
In this change, ICL_OVERRIDE/APSD and USB mode are updated, so
that PD can alter current limit by simply voting the ICL
setting.

Do not dump PCIe PHY and PARF register space when there is
a linkdown. By the time PCIe receives the linkdown interrupt,
the reset for PCIe PHY has already happened, so these registers
do not have any meaningful value.

xHC gets powered down when host mode is stopped. xHCI power
management is intended for ACPI based power management which
is defined for PC architecture. Hence there is no need to
clear run/stop bit and save the runtime register states upon
port suspend.

Sink may issue attention event faster then it can be processed by
source. Create a list of attention events and process them one by
one in the order on workqueue to avoid missing any attention event
from sink.

HDCP authentication requires valid keys on the source device.
If keys are not present, authentication can never be successful.
Check if the device is provisioned with hdcp keys, if so, proceed
with the hdcp authentication on HDMI/DisplayPort cable connection
otherwise avoid authentication as it may result in unnecessary
re-authentication loop.

ARRAY_SIZE returns size of array. While sending command string
we need to only pass size of actual command string, hence use
strlen in place of ARRAY_SIZE.

Migrate tasks function is used by both hotplug and cpu isolation. During
hotplug all the cpus are stalled (in stop machine) while tasks are being
migrated. However, this is not the case during cpu isolation. A task
that was counted as a pinned thread might have been migrated off the
cpu. Take this into account when checking whether we have completed
moving all tasks off the runqueue.
Also ignore warning about tasks moving off the run-queue for isolation
use case.

Cluster cpu list traversal is not properly protected against removal of
element by a separate thread. Add proper locking to ensure an element
cannot be removed while accessing the list.
In addition ensure we don't end up in a livelock never exiting the loop
due to hotplug continuously moving elements to the end of the list.
