ANDROID: fix kernelci build breaks for dcn_calcs

A backport of an amd display change changed several local variables into
pointers without updating how they were passed in to subsequent function
calls.

Fixes the following kernelci build errors:
- ‘input’ is a pointer; did you mean to use ‘->’?
- incompatible type for argument 3 of ‘dml1_extract_rq_regs’
- incompatible type for argument 5 of ‘dml1_rq_dlg_get_dlg_params’
- incompatible type for argument 6 of ‘dml1_rq_dlg_get_dlg_params’
