When v4l2 streamon() is called the framework moves to streamon state,
after queueing the buffer. A state check is performed during dqbuf().
Sometimes when dqbuf() is called streamon() function has not completed
setting the state transisiton flag. This results in failure to dqbuf() as
the framework has not moved to streamon. This patch adds a mutex
around state transitions and dqbuf() calls.

Currently when VFE requests for a free buffer, we search based
on the image mode sent from VFE. In some cases, there can be
multiple instances with the same image mode. This means the
buffer lookup logic has to take into consideration other
parameters like current usecase, vfe operation mode etc.
To ease this, add support for buffer lookup based on
the instance handle. The instance handle contains information
about where to get the buffer from. So the buffer lookup
logic does not have to know about other details. The instance
handle is decided when the user sets the format for a particular
instance. It is passed on to the VFE during AXI configuration.
VFE stores this and sends it whenever it requests for a free
buffer for a particular output.
Keep the current image_mode based buffer lookup logic for
legacy targets.

Closing VCAP devices could be called without calling stream off:
This problem would make VCAP resources taken by devices no longer
running.
Using unsigned variable to store signed result: This problem would
allow stream on to continue even when function returned error.
Fix problem of reading VP irq status register too early: It was
possible for cadence detection bit to be propgated faster by only
a few clock cycles then the picture done bit. When the irq status
read was performed and by the time a write to the clear register
was performed the picture done bit would propgate. Since the irq
is rising edge triggered this would cause a problem and the irq
would not be triggered until VP was reset.

This change fixes a crash when running VCAP in de-interlace mode.
The problem was noticed in the introduction of kernel 3.4. VCAP
was improperly using the videobuf2 framework APIs. Since VCAP is
already reliant on queue structure provided by videobuf2 framework,
we created our own basic version of the qbuf and dqbuf calls that
have some similarities to the videobuf2 framework. This addition
was necessary since we are calling qbuf from a kernel work thread.
Since moving to kernel 3.4 there has been a change in videobuf2
qbuf that dereferences the current process.s mm_struct, from a
kernel work thread this struct is NULL, which was causing a crash.
When we are de-interlacing a captured video we are cycling the
buffers internally in the driver, which is why we needed to create
our own q/dq buffer functionality.

Add initial driver code for IRQ Router hardware.
It shall be implemented as a v4l2 subdevice of the
msm cam server node.
Add logic in msm cam server to request for irqs configured
to the IRQ Router, which can be individual or composite.
When the individual camera hardware cores interrupt,
the cam server receives them through the common interrupt
handler and dispatches them to to the respective hardware
core's v4l2 subdevice.
If the usecase demands that the interrupts from two
different hw cores be composited into a single interrupt,
(for eg: VFE and ISPIF), then the cam server stores this
configuration in its interrupt lookup table. When the
interrupt is triggered on the composited interrupt,
it is dispatched to the individual hardware cores
which have been composited into that interrupt.
