sound control 3.x: Initial GPL release for WCD9310 Audio Codec

This is first official GPL release based on my private implementation.

This release has been tested for Mako and Flo officially.  It may work
with other devices using the same WCD9310 Audio Codec as well, but not tested

msm: msm_bus: Fix the 64-bit division during interleaving

When interleaving flag is enabled, the bandwidth is divided
between ports. There was an error in the division as the
macro was not correctly updated with the right order of using
bandwidth and port number when 64-bit division function
was used by the bus driver.
Correcting this for fixing the token allocation issues
observed.

msm: msm_bus: Change MDP port interleaved setting

When display driver requests bandwidth on MDP port 0, it was
automatically divided between port 0 and port 1 by the bus driver
as a part of interleaving. Since MDP port 1 was never used,
this did not have any impact.

Now, the display driver needs to use MDP port 1 such that MDP
ports should be able to use the bandwidth non-uniformally.
To enable these ports to use unequal amount of bandwidth,
it is required that bus driver does not divide bandwidth
between port 0 and port 1.
The display team is now responsible for requesting bandwidth
explicitly on both ports.

msm: msm_bus: Add NULL pointer checks.

Bus driver is crashing due to a NULL pointer
access sent by the client. A few NULL pointer
checks have been added to protect the driver
from invalid/NULL client handle.

msm: msm_bus: Explicitly clear client requests before removal

Clients can potentially leave non-zero requests before
unregistering. Such requests persist and cause instability
and severe power and performance impact.

Protect the system against such clients by explicitly
clearing the client requests before unregistration

On failure, return 0, and not a non-zero value as that can
