Add CEC notifier support which allows HDMI driver to
inform CEC driver with the new physical address. With
this information the CEC adapter driver does not need
to manually set the physical address from userspace.

Add support for CEC notifiers, which is used to convey CEC physical address
information from video drivers to their CEC counterpart driver(s).
Based on an earlier version from Russell King:
https://patchwork.kernel.org/patch/9277043/
The cec_notifier is a reference counted object containing the CEC physical address
state of a video device.
When a new notifier is registered the current state will be reported to
that notifier at registration time.

This CEC adapter driver using CEC framework provides CEC
support for SDE hardware. CEC is a protocol that provides
high-level control functions between various audiovisual
products. This adapter is the hardware implementation of
CEC protocol, and its major functionality is to send and
to receive CEC messages.

When calling smmu mapping, if iova is specified directly by user, not
allocated dynamically in dma-mapping.c, smmu driver needs to provide
support for this. This is needed in early display case. In this scenario,
LK has set physical memory to display hardware for fetching, so if iova
is not explicitly specified in kernel, but instead dynamically produced
by "alloc_iova" in dma-mapping.c, display hardware has no chance to know
this new iova, then smmu fault will happen if enabling the iommu stage-1
translation.
To fix this smmu fault problem, add re-routing to the right path when
iova specified by user is not 0 in smmu map/unmap function.

USB connector HW based thermal regulation is active which will throttle
the input current on USBIN-USBIN configurations. This was enabled for
MID-MID configurations to enable the comparator output for USB connector
temperature mitigation, but since the input is bypassed it does not
throttle the input current. The comparator output is no longer used
since the ADC values are used directly, so neither configuration needs
this HW feature to be enabled.
Remove the write to enable this HW feature.

As per USB PD 3.0 specification the 2-bit Specification Revision field
of a GoodCRC Message does not carry any meaning and Shall be considered
as don't care by the recipient of the Message. Hence set spec revision
to USBPD_REV_20 for GoodCRC message. PD protocol message header defaults
to USBPD_REV_20 which gets updated USBPD_REV_30 if PD 3.0 source capabale
of programmable power supply.

Sigdet under low power (LP) mode will use a less accurate local reference
generation, which is expected to have a little more variation than a
precise reference (normal mode). Update PCIe PHY sigdet to use normal
mode instead of LP to increase accuracy and make sigdet more robust.

Allow re-configuring the DSI, DP and HDMI RCGs even if their
current configuration matches that of the requested frequency.
This is to work around the MM RCGs being latched to run off of
XO by default after an MM GDSC power collapse.
