drm/msm/dpu: Drop encoder vsync_event
...
Drop vsync_event and vsync_event_work handlers as they are unnecessary.
In addition drop the dpu_enc_ktime_template event class as it will be
unused after the vsync_event handlers are dropped.

drm/msm/dpu: remove struct drm_dsc_config from struct msm_display_info

Since struct drm_dsc_config is stored at atomic_enable() instead
of display setup time during boot up, saving struct drm_dsc_config
at struct msm_display_info is not necessary. Lets drop the dsc member

drm/msm/dpu: retrieve DSI DSC struct through priv->dsi[0]
...
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

dpu_encoder_helper_phys_cleanup() was not populating neither

- Loop over all drm_encs connected to crtc
Changes since V2:
- Remove vblank.h inclusion
- Change `pos + i` to `pos + entries`
- Initialize values_cnt to 0 for encoder
- Change DPU_CRTC_CRC_SOURCE_INTF to DPU_CRTC_CRC_SOURCE_ENCODER (and
"intf" to "enc")
- Change dpu_encoder_get_num_phys to dpu_encoder_get_num_hw_intfs
- Add checks for setup_misr and collect_misr in
dpu_encoder_get_num_hw_intfs
Changes since V3:
- Remove extra whitespace
- Change "enc" to "encoder"
- Move crcs array to dpu_crtc_get_encoder_crc

state so need not be allocated during dpu_encoder_virt_atomic_mode_set().

Since dpu_encoder_setup_display() already has protection against
setting invalid intf_idx and wb_idx, these checks can now
be dropped as well.

drm/msm/dpu: Increment vsync_cnt before waking up userspace
...
The 'vsync_cnt' is used to count the number of frames for a crtc.
Unfortunately, we increment the count after waking up userspace via
dpu_crtc_vblank_callback() calling drm_crtc_handle_vblank().
drm_crtc_handle_vblank() wakes up userspace processes that have called
drm_wait_vblank_ioctl(), and if that ioctl is expecting the count to
increase it won't.
Increment the count before calling into the drm APIs so that we don't
have to worry about ordering the increment with anything else in drm.
This fixes a software video decode test that fails to see frame counts
increase on Trogdor boards.
