Remove false positives for locks acquired with trylock.
Trylock was not recording the timestamp when the lock was
acquired. Therefore an old timestamp was used when releasing
the lock and the infrastructure would report that the lock
was held for longer than it was.
With the infrastructure set to generate a crash when a lock
is held too long, these false positives make the system unstable.

Adding lock stats print upon spinlock & mutex destroy.
The spinlock destroy of the lro unloading lock in the
napi context did not match the create in location.
When a station adapter goes down and is brought back up,
the mismatch appears.

The Common subsystem shutdown is allowed after the irq_enable
register is written. A race condition in host (multiple other
interrupts firing on the same core). Can delay the register read
and allow the common sub system to be shutdown before the read.
The read would then cause an SNOC error as the register is unclocked.

Allow qdf to print messages without including qdf_trace headers.

The api qdf_get_log_timestamp is the fastest way to get a

apis for logging time differences in human readible quantities.
This also adds the reverse conversion.

Create debug file system entries to show current QDF memory usage.
The 'list' option adds a little overhead, which is minimized by
locking node by node while traversing the entire allocated memory
list. Major operation is lock-less, using node reference count.
Following debugfs entries are added,
1. /sys/kernel/debug/<module_name>_qdf/mem/list
This lists QDF allocation by file and line number. It takes
some time to traverse the entire allocated list.
2. /sys/kernel/debug/<module_name>_qdf/mem/kmalloc
This file shows total kmalloc done by qdf_mem_alloc().
3. /sys/kernel/debug/<module_name>_qdf/mem/dma
This file shows total allocation done by qdf_mem_alloc_consistent()

Create a root directory for debugfs at
/sys/kernel/debug/KBUILD_MODNAME_qdf/. The module name,
KBUILD_MODNAME, is used in the path to avoid conflict in case of
multiple instances of the same driver.
Any sub module in QDF can use this as the root directory to add
further files of directories. While unloading the driver the exit
routine does a recursive cleanup of any remaining files or
sub directories.
Even though debugfs is a Linux specific feature, a logic which is
related to file system for debugging can be added here.
This feature is protected with a compilation flag WLAN_DEBUGFS.
