msm: camera: uapi: new structure for SAT frame sync

New SAT SW frame sync requirement needs support 3 or 4 concurrent
cameras working at the same time. Only 2 cameras crrently supported.
Change adds new structure to support more than 2 camera scenario,
using dynamic array to avoid changing when extend cameras.
