msm: camera: ife: Enable sample drop on CSID RDI paths

This change enables CSID sample drop on RDI paths by default. The
sample drop pattern, as always, is set to 0 at init. This allows
the userspace driver to simply program sample drop pattern on
desired RDI paths to obtain sample dropped output without having
to also overwrite config register to enable drop. This change
also takes care of programming max value to sample drop period on
version 480 hardware due to hardware limitations. It also adds a
separate header file for CSID Lite version 480 hardware.
