Per DP spec, for active protocol convertor adaptor, DP source should enable audio
for DFP type is DP, HDMI or DP++. Current is_dp_active_dongle() checking is not
precise, which treat branch device default as active dongle. As a result, we will
mistakenly disable audio for DFP type is DP case.
[How]

[WHY]
To process AUX transactions with DMUB using inbox1 and outbox1 mail boxes.
[How]
1) Added inbox1 command DMUB_CMD__DP_AUX_ACCESS to issue AUX commands
to DMUB in dc_process_dmub_aux_transfer_async(). DMUB processes AUX cmd
with DCN and sends reply back in an outbox1 message triggering an
outbox1 interrupt to driver.
2) In existing driver implementation, AUX commands are processed
synchronously by configuring DCN reg. But in DMUB AUX, driver sends an
inbox1 message and waits for a conditional variable (CV) which will be
signaled by outbox1 ISR.
3) DM will retrieve Outbox1 message and send back reply to upper layer
and complete the AUX command

Our driver supports overlay planes, and as expected, some userspace
compositor takes advantage of these features. If the userspace is not
enabling the cursor, they can use multiple planes as they please.
Nevertheless, we start to have constraints when userspace tries to
enable hardware cursor with various planes. Basically, we cannot draw
the cursor at the same size and position on two separated pipes since it
uses extra bandwidth and DML only run with one cursor.
For those reasons, when we enable hardware cursor and multiple planes,
our driver should accept variations like the ones described below:
+-------------+ +--------------+
| +---------+ | | |
| |Primary | | | Primary |
| | | | | Overlay |
| +---------+ | | |
|Overlay | | |
+-------------+ +--------------+
In this scenario, we can have the desktop UI in the overlay and some
other framebuffer attached to the primary plane (e.g., video). However,
userspace needs to obey some rules and avoid scenarios like the ones
described below (when enabling hw cursor):
+--------+
|Overlay |
+-------------+ +-----+-------+ +-| |--+
| +--------+ | +--------+ | | +--------+ |
| |Overlay | | |Overlay | | | |
| | | | | | | | |
| +--------+ | +--------+ | | |
| Primary | | Primary | | Primary |
+-------------+ +-------------+ +-------------+
+-------------+ +-------------+
| +--------+ | Primary |
| |Overlay | | |
| | | | |
| +--------+ | +--------+ |
| Primary | | |Overlay | |
+-------------+ +-| |--+
+--------+
If the userspace violates some of the above scenarios, our driver needs
to reject the commit; otherwise, we can have unexpected behavior. Since
we don't have a proper driver validation for the above case, we can see
some problems like a duplicate cursor in applications that use multiple
planes. This commit fixes the cursor issue and others by adding adequate
verification for multiple planes.
Change since V1 (Harry and Sean):
- Remove cursor verification from the equation.
