Update LPA platform driver to register restart callback.
The implementation of the callback is to issue a pending buffer
written by the application to restart the session when the dequeue
process is stopped due to underrun issue.
The callback is triggered from ALSA core when the framework
detects that the renderer stopped pulling data but the application
is still writing data. It runs in atomic context.
Fixes:
-A disturbance was heard when switching from one song
to the other, or when the song is paused for greater
than 3 seconds and then resumed
-This was due to the previous value of the track
volume being used in the lpa driver
-This was fixed by setting 0 as the initial volume

It is desirable for performance reasons to be able to run dcvs
with different algorithm parameters depending on the number of
CPUs that are online. The algorithm parameters are already replicated
per-CPU, but all CPUs operate in DCVS with the same parameters at
any given time.
These per-CPU parameters now correspond to the total number of CPUs
online. For example, if 2 CPUs are online, the algorithm parameters
for CPU2 are used.

With 8974, bandwidth requests are exceeding integer size.
Update ab and ib to ensure values over 4Gbps can be requested.
For 64-bit support, there are four changes in this patch:
Changes in the bus driver structures and functions to
update ab and ib values to uint64.
Updates in client drivers to ensure that the bus APIs
are called with the right types.
Updates to the device-tree. Device-tree nodes don't
provide a clean mechanism to read a combination of u32
and u64 variables within the same property name. So, the
ab and ib values must be specified in kbps instead of
bytes/sec from the device tree. The bus driver function
will convert the ab and ib values read from device-tree
to Mbps.
Change the existing property names to make them consistent
with the convention used by the new property name, which
abides to the Device Tree convention.

Adreno idle detection during a hang was being obstructed when
called from adreno_waittimestamp(). The variable active_cnt which
was meant to protect the device from going into suspend while
doing a waittimestamp was being set and was preventing the
check of rbbm_status register which was leading to a false hang
detection, where, if the rbbm_status register value had been
probed the device would have been found to be idle. We fix this by
having a separate function is_adreno_rbbm_status_idle() which checks
this register and report whether the core is idle or not. And we call
this function instead of the generic adreno_isidle() inside
adreno_hang_detect(). Doing this fixes at least one scenario of false
hang detection.
