drm/msm/dpu: get rid of struct dpu_rm_requirements

The struct dpu_rm_requirements was used to wrap display topology and
hw resources, which meant INTF indices. As of commit ef58e0ad
("drm/msm/dpu: get INTF blocks directly rather than through RM") the hw
resources struct was removed, leaving struct dpu_rm_requirements
containing a single field (topology). Remove the useless wrapper.
