In PMICv2, typec removal is known when CC detachment is detected,
but this does not work due to a HW bug, when orientation is CC2
with medium or high rd.
Currently in HW, after cable is removed, rd reading switches to
std from medium or high. The software workaround is to catch this
very change in cc state update, and then force a cc detach irq.

In PMICv2, typec removal relies on CC detachment detection,
but CC removal event does not fire when orientation is CC2
with rdstd, due to a HW bug.
The software workaround is to force typec sink cycles and
poll CC states, until cc status reading confirms detachment,
and PD is notified of typec removal.

Enabling L1 / L1SS for 11ad device causes PCIe
link down or PCIe NOC read/write timeouts.
To prevent that, disable L1 for 11ad devices after
PCIe enumeration and resume.

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.

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.
