defconfig: msm: new flag for mediabox specific demux changes

For Mediabox project demux requires raise video frame events
only for MPEG-2 B frames and H264 non idr frames instead of all
frames. These changes are required for clock recovery & AV sync
for mediabox project.

fuse: fix use after free issue in fuse_dev_do_read()

There is a potential race between fuse_dev_do_write()
and request_wait_answer() contexts as shown below:

TASK 1:
__fuse_request_send():
  |--spin_lock(&fiq->waitq.lock);
  |--queue_request();
  |--spin_unlock(&fiq->waitq.lock);
  |--request_wait_answer():
       |--if (test_bit(FR_SENT, &req->flags))
       <gets pre-empted after it is validated true>  TASK 2:
             fuse_dev_do_write():
       |--clears bit FR_SENT,
       |--request_end():
          |--sets bit FR_FINISHED
  |--spin_lock(&fiq->waitq.lock);
  |--list_del_init(&req->intr_entry);
  |--spin_unlock(&fiq->waitq.lock);
  |--fuse_put_request();
       |--queue_interrupt();
       <request gets queued to interrupts list>
            |--wake_up_locked(&fiq->waitq);
       |--wait_event_freezable();
       <as FR_FINISHED is set, it returns and then
       the caller frees this request>

Now, the next fuse_dev_do_read(), see interrupts list is not empty
and then calls fuse_read_interrupt() which tries to access the request
which is already free'd and gets the below crash:

[11432.401266] Unable to handle kernel paging request at virtual address
6b6b6b6b6b6b6b6b
...
[11432.456168] PC is at __list_del_entry+0x6c/0xc4
[11432.463573] LR is at fuse_dev_do_read+0x1ac/0x474
...
[11432.679999] __list_del_entry+0x6c/0xc4
[11432.687794] fuse_dev_do_read+0x1ac/0x474

[11432.699082] __vfs_read+0xc0/0xe8
[11432.704459] vfs_read+0x90/0x108

As FR_FINISHED bit is set before deleting the intr_entry with input
queue lock in request completion path, do the testing of this flag and
queueing atomically with the same lock in queue_interrupt().

ARM: dts: msm: Config sdm660 CPR controllers to use default step_quot

There is a chance for a CPR controller to use the run-time calibrated
step_quot of lower modes for higher modes. This can sometimes lead
to closed-loop voltage getting stuck at open-loop voltage. To avoid
this, configure APC0/1 and GFX CPR controllers in sdm660 to first use
the default step_quot and then later switch to the run-time calibrated
step_quot.

Current driver has two votables for controlling the usb current

the icl votable changes current setting while its suspended.
Changing current setting while suspended causes icl changed
interrupt storm.

Fix it by removing usb_suspend_votable and make all the suspend

Update usb_icl_votable to update current settings only when
not suspended. Moreover disable the interrupt while changing
