This change acquires the vm lock before pre-releasing the
dependent drivers. This avoids any race condition on any
parallel async commands transfers scheduled on connector
drivers. Additionally the main irq line is only disabled
after the pre-release to allow any ongoing transfers
to complete.

This change reinitializes the sde_crtc->mixers when CTL
datapath switch occurs during mode set and RM allocation
of CTL hw block is changed. This initialization is required
for CTL_LAYER programming to trigger on the new CTL allocated
from RM.
Issue case:
1. Primary Display is using CTL_0 and it is reserved.
2. Secondary Display is using CTL_1. On suspend, RM adds
CTL_1 into the free list.
3. External Display is powered on, RM allocates CTL_1 hw blk.
4. Secondary Display is powered on, RM allocated CTL_2 hw blk.
5. External Display is suspended/unplugged, RM adds CTL_1 into
the free list.
6. When any mode_set(say fps switch) occurs on secondary, RM
allocates new resources and CTL_1 is allocated.
sde_crtc->num_mixers is non zero, so all the layer programming
happens on CTL_2, but CTL_1_FLUSH bits are programmed causing
hw timeout issue.

MDSS.9.0 adds support for mdp vsync based HW timestamps
on top the existing support for panel vsync based timestamps.
This allows us to enable vsync timestamp calculations for all the
use cases including a few corner cases (e.g. programmable fetch)
which we couldn't support with the existing HW.
This change adds the new HW register support and modifies the
timestamp read logic to use mdp vsync on supporting targets.

From Kalama, the HW scheduler abstracts the low level
PP_DONE/WB_DONE interrupts and generates a common
CTL_DONE interrupt per hw ctl. This saves the software
the irq latency delays to process the frame complete
operations when multiple encoders are involved.
If supported, this change enables and waits for the
CTL_DONE interrupt instead of PP_DONE and WB_DONE.
This change adds support to wait for CTL_DONE irq in
only command mode panels as we don't drive two WB blocks
with single CTL.
