Set a flag to avoid multiple reading of sde_dbg info, that
reduces devcoredump reading time.

Add devcoredump support for sde_dbg. Devcoredump is a mechanism
providing generalized way to get data from kernel modules. This change
integrates devcoredump into sde_dbg to get evtlog, register dump and
dbg_bus when display failure happens.

Large allocations using kzalloc can lead to timeouts. This updates
the allocation calls accordingly to use vzalloc to remove
requirements on contiguous memory.

Event logs are restricted to be logged only with IN_LOG option during
a SDE_DBG_DUMP() call. Extend the logging support to IN_LOG_LIMITED
option. The option is set to IN_MEM by default and can be changed
through debugfs.

Add support to use atomic variable instead of spinlog
for event log while adding enries. This change will
help optimize event log writing time.

Add support to use atomic variable instead of spinlock
for register logs during register write. This change
helps in reducing the run-time and is safe to use as
most of the register writes happen in commit context.

This change uses kvzalloc to allocate memory for eventlog and register
dumps. This is needed since kernel cannot guarantee that physically
contiguous allocations greater than 32 KB will succeed.
Additionally it reduces the number of entries for evt logs and
register dumps for trusted vm.

Avoid printing the eventlogs in kernel logs during display debug
logging through sde_dbg_dump to avoid excessive logging. Add a
debugfs node to control in-mem/in-log mode of eventlogs to help
in debugging.

The display driver uses ktime_to_us to timestamp the messages
in the sde event log. But the kernel logs use local_clock to
timestamp the messages. Using same timestamp routine in sde event
log helps to correlate the messages from both the logs
for debug purpose.
