We cant use active status check for specific pads under calibration.
This is common bit for all pads.
I'm not sure why this is a problem.

IIUC, the start_calibration() should wait for the MIPI_CAL_STATUS_ACTIVE
and finish_calibration() should wait for MIPI_AUTO_CAL_DONE_CSIA/B.

As soon as START bit it set, FSM will set ACTIVE = 1

There is no added advantage of waiting for ACTIVE to be in start_calibration()
