media: imx: imx7_mipi_csis: Minimize locking in get/set format

Browse source

Reduce the code sections that are run with the lock held in the get/set
format handlers:

- mipi_csis_get_format() retrieves a pointer to the format, and thus
  doesn't need locking as long as the arguments passed to the function
  don't require locking either.

- sdformat is a structure passed by the caller, not an internal state,
  and thus doesn't require locking.
