Current display driver prints warnings and errors within
the mdss spinlock. This causes in random cases to hold the
spinlock for long time when multiple errors are printed;
Fix this by moving the print of warning and error messages
outside of the spinlock.

for printing kernel pointers which should be hidden from unprivileged
users, use %pK which evaluates whether kptr_restrict is set.

Add support for CEC commands to suspend and resume the device.
The HDMI core must be kept on when the CEC wakeup feature is
enabled and the device is going into suspend state. Furthermore,
interrupts must be enabled in this state to capture CEC commands.
This allows the device to be resumed later on via CEC wakeup commands.

Hardware might return/call the pending interrupt
on one CPU when same interrupt is disabled from other
core. Such parallel processing may lead to unclocked
register access in interrupt context followed by
panic. It is safe to check the interrupt line status
before handling isr to avoid crash in such race
condition.

In the current implementation, the continuous splash screen flag
is set based on whether there is handoff pending in MDP or not.
With the dual DSI use-case now in place, there is possibility that
the primary panel has continuous splash enabled whereas the other
panel doesn't have the feature enabled. Add change to take care of
this by checking if a particular interface is enabled in MDP_INTF_SEL
register to set the cont. splash screen flag. Remove the DT entries
for continuous splash screen since it is no longer needed after this
change.

Add get panel configuration and get iommu domain functions to
common utility interface. This will make sure that DSI 6G gets
the right information on ferrum which has mdp3.

msm8909 has mdp3 with DSI 6G. Enable DSI 6G to work with
mdp3 and mdp5 while using iommu and bandwidth functions.

In ferrum DSI has an irq line which is different from mdp.
Add support for irq handling this case. It makes use of
utility functions provided by mdss.

Change irq interface provided by mdp from exporting symbols to
function pointers. This will help in making mdp3 work with dsi 6G.
