drm/msm/dpu: add current resource allocation to dumped state

Browse source

Provide atomic_print_state callback to the DPU's private object. This
way the debugfs/dri/0/state will also include RM's internal state.

Example output (RB5 board, HDMI and writeback encoder enabled)

resource mapping:
	pingpong=31 36 # # # # - - - - -
	mixer=31 36 # # # # -
	ctl=# # 31 36 # #
	dspp=# # # #
	dsc=# # # # - -
	cdm=#
