From: David Zhang <dingchen.zh...@amd.com>
[Why]
In cases where there are multiple eDP instances, DMUB needs to know
which instance the command is for. Today, the field for specifying the
panel_inst exists in both dmub_cmd_update_dirty_rect_data and
dmub_cmd_update_cursor_info_data.
For cursor updates, we already specify the panel_inst, but that's not
the case for dirty_rect updates. Today, a value of '0' is used (due
to initial memsetting of the cmd struct to 0)
[how]
In dc_dmub_update_dirty_rect(), Call dc_get_edp_link_panel_inst() to get
the panel_inst, and fill it in the DMUB cmd struct.
v2: Update commit message for clarity.
