Currently when entering touch-to-wakeup (TTW) mode, IBB module
is disabled as part of the regulator_disable sequence before
applying the settings needed for SWIRE control in TTW mode.
This causes adversary effects such as droop in the VDISN
voltage rail.
To avoid this, as per the hardware documentation, do not disable
IBB module through IBB_ENABLE_CTL when LABIBB regulators are
disabled and entering TTW mode. Instead, just enter TTW mode and
mark the regulators disabled. Normal mode settings will be
applied when the regulators are enabled again as before.
While at it, add a centralized function qpnp_ibb_mode() to write
to IBB_ENABLE_CTL register.

It is possible that the ULPS entry request can potentially overlap with
the last DCS command that was sent out on the link. This is more likely
if the DCS command was sent in LP mode. In such cases, the panel could
see some issues in the LP transmission which may trigger an error when a
BTA is done subsequently. To address this, ensure that the lanes are
idle by checking that all active FIFOs are empty and the all active data
lanes are in stop state.

The ctl_stop and vsync_handler both can run in two different
threads. That can lead to race condition in vsync handler.
-> Core 0: vsync handler thread checks the ctl power status
and get preempted by other priority task.
-> Core 1: processes the ctl_stop and power off the display
device.
-> Core 0: Vsync handler task gets chance to run again and
tries to access the ctl->op members.
The third step leads to invalid structure member access because
display is already powered off. This race condition should be
fixed by moving all power state checks inside mutex lock.
