This is to avoid race condition which can cause buffer overflows.

The v4l2 event handler struct should be initialized
before added to the dev_ctxt->instances list.
The v4l2 event handler struct should be de-initialized
after we remove inst from the core->instances list.

Create bridge abstraction driver to provide a framework that can be
used to abstract different types of bridge chips under a common API.
The framework also allows multiple drivers to control different
functional aspects of a bridge chip.
The bridge abstraction driver is limited to bridge chips that deal
with converting audio/video data from one protocol to a different one.

According to the PD 2.0 Spec, Section 6.2.1.3, the MessageID
field shall only be incremented upon successful transmission
(meaning GoodCRC was received). Thus, increment the counter
only when pd_phy_write() succeeds.

Currently, there is an incorrect programming of the
hdmi controller register where default value of the
datapath mode bit is being toggled along with the
scrambler enable/disable.
This bit should be untouched as per the hardware
programming sequence and kept at the default state.
Fix the register programming to avoid toggling this
bit.
