All other submodules pass arguments directly. Drop struct
msm_dp_panel_in that is used to wrap dp_panel's submodule args and pass
all data to msm_dp_panel_get() directly.

Change not necessarily tied to catalog cleanup, and can be sent
independently IMO.

so this API, takes a filled input panel, makes a msm_dp_panel out of it
by filling out more information on top of what was already passed in and
returns a msm_dp_panel.
So IOW, converts a msm_dp_panel_in to msm_dp_panel.
What is the gain by passing individual params rather than passing them
as a struct instead? Isnt it better to have it within that struct to
show the conversion and moreover we dont have to pass in 4 arguments
instead of 1.
