msm: vidc: Migrate to kernel 3.10

Migrate to kernel 3.10 which has contains minor changes in the
V4L2 interface:
- Driver needs to specify how it provides timestamps
- Driver needs to declare itself as a mem2mem driver so that
  certain ioctls are not masked out before reaching the driver.
- Vendor specific buffer flags have been changed as to not
  conflict with standard flags
- Controls that are of boolean type need to explicitly set the
  step to 1.
