M2: camera: Enable CAMIF SOF in case of non dual camera usecase.

When Dual camera usecase is enabled, the ISPIF PIX SOF is enabled
by default to synchronize with the RDI interfaces.
But in non dual camera usecases, use CAMIF SOF IRQ to increment
the frame IDs being embedded inside the output frames.
Sometimes the SOF IRQs of frame 'n' is clubbed along with the
Output IRQs of the frame 'n-1'. Thus although the output IRQs
are supposed for frame 'n-1' it results in a frame ID of 'n' which
will cause incorrect behaviour downstream. Correct this behaviour
by checking the SOF and Output status bits in the IRQ Mask and
adjust the frame ID accordingly.

*detule: Also add similar checks for camif + stats irqs (as in upstream
driver)
