Currently struct drm_dsc_config for DSI is populated at display
setup during system boot up. This mechanism works fine with
embedded display but not for pluggable displays as the
struct drm_dsc_config will become stale once external display
is unplugged.
In preparation of adding support for DP DSC support
move storing of DSI DSC struct to atomic_enable() so that same
mechanism will work for both embedded display and pluggable
displays.
Changes in v4:
-- fix checkpatch.pl warning
Changes in v5:
-- delete dpu_encoder_get_dsc_config() from atomic_mode_set
