Adds support for new mink call to configure secure camera sessions. This new mink call takes in additional parameters to support the new domain-id based security scheme. The additional parameters are in the form of csid_hw_idx_mask, cdm_hw_idx_mask and vc_mask. These are in addition to the existing PHY idx and CPHY/DPHY lanes info. The introduction of this new mink call deprecates the existing SCM call used to service secure camera sessions. What this means is that on all subsequent versions of this driver, all secure camera sessions will be serviced by this mink call, which is able to accommodate older and newer targets, and their programming of different register sets. This design enables the cam_csiphy_notify_secure_mode wrapper to remain the same, with the underlying mink call made in the cam_compat layer, depending on camera driver version.
