Add changes to modify the phys_enc->in_clone_mode variable
post wb_reset_state since this is a shared variable used
during atomic_check and atomic_commit. In current issue case,
wb_atomic_check has set in_clone_mode to true in commit N,
and in commit N-1 CWB is being disabled and re-sets the
in_clone_mode variable to false causing pp_done timeouts in
primary in commit N.

This reverts commit 0623a02a84. It leads to
panic during smmu faults because we do not have any recovery. Reverting
this will give the control to the client to dump if necessary.

In PM resume with CWB concurrency usecase, crtc pointer in
conn->state is NULL since drm_mode_config_reset operation is
performed on pm_resume. This change relies on conn_mask in
new_crtc_state for primary connector retrieval and also adds
get_num_lm_from_mode callback to DSI for LM count retrieval
from dsi panel topology. Existing get_mode_info api cannot
retrieve the topology info because mode->priv_info is NULL.
This occurs as WB encoder is added in the drm encoder_list
before primary encoder, introduced as part of commit d28ebf05f4
("disp: msm: sde: populate WB display encoder list before dsi").

option. The option is set to IN_MEM by default and can be changed

The DMA buffers used by the display module are cached buffers. While
mapping to the CPU, pgprot_writecombine should only be used for uncached
buffers. The change fixes this mismatch during virtual address mapping.

Some panels may require that the DSI link returns to the low-power
stop state (LP11) after transmission of every line. If a panel
requires that the DSI link returns to LP11, apply the LP11
insertion between lines feature.
This change adds support to
- Disable the command mdp burst mode
- Enable mdp idle ctrl
- Program the No. of dsi pclk cycles of idle time to
insert between command mode mdp packets. The idle time
must be long enough to cover the time link takes to
switch between HS to LP11 mode.
