msm: sde: Provide better error logging in SDE rotator

During streamon, sde rotator needs to perform a final input and output
format validation. If the validation fails during streamon, it is better
to provide error logging. However, during V4L2 parameters setup phase,
the driver should not report error message because it is normal to have
invalid setting and client can retry with other setting. This change
will separate those two scenarios and only generate error logging
during streamon. Also add additional logging during rotator timeout
and VBIF registers dump in ramdump.
