BAM (DMA) can transfer the data of any length or alignment.
Currenly we are using the BAM only if SDCC transfer size
is less than FIFO_SIZE (64 bytes) and only if it's in multiple
of FIFO_SIZE.
As BAM doesn't have any limitation on the minimunm size of the
request, we can use the BAM even for transfers of less than
FIFO_SIZE but performance profiling has proved that using PIO
mode (no DMA) for transfers <= FIFO_SIZE is better compared to
BAM mode.
So this change uses the BAM only if transfer size is greater than
FIFO_SIZE but removes the restriction that transfer size must be
in multiple of FIFO_SIZE.

Once core0 comes out of the PC, it uses the IPC1 interrupt to wake up
the core1 out of the sleep(GDFS). Since this interrupt is intended to
core1, move the clearing of this interrupt from core0 to core1 context.
Remove the masking and umnaking of IPC1, as no other driver is going
to use this interupt.

- Reorganize camera io functions by putting all the
common APIs in the util file.
- Move all the hardware
specific IO files into the io folder.
- The io functions used by the camera driver are named
as msm_io_* even though they are camera specific.
Rename them to msm_camera_io_*.

Code executing in process context should use hci_dev_lock_bh()
and hci_dev_unlock_bh() instead of hci_dev_lock/hci_dev_unlock
when dealing with the hci_dev lock so that it cannot be
interrupted while the lock is held.

Add support for "set all message masks" and "disable logging"
requests.
Also, avoid sending event mask update when not required. DIAG driver
propagates event mask updates, when a remote peripheral boots up.
Sometimes, the event masks are not even set yet, when a remote
peripheral comes up. In such cases, there is no need to send
mask updates.

Change the vmalloc allocation name to something more appropriate since
we do not allocate memory using vmalloc for userspace driver. We
directly allocate physical pages and map that to user address space. The
name is changed to page_alloc instead of vmalloc. Add sysfs files to
track memory usage via both vmalloc and page_alloc.

The actuator functionality is the same for different camera
modules. So a single actuator driver module is supported.
The variation is because of actuator control parameters,
which are made available in user space actuator driver
for better integration with tools used for autofocus
tuning.
