In hypervisor system, lock may hold too long due to context switches
and system calls at host which is leading to stolen time. Sometimes
this delay will be larger than 100 ms.
To address this issue, it needs to increase irq save spin lock detection
threshold to 100+ ms for hypervisor system.

With restructured internal hif runtime pm. Modules using the
runtime pm module need to get registered with runtime pm modules
with their static IDs. QDF wrappers for allowing and preventing
runtime pm suspend are depreciated.
This change introduces ID for various modules and new qdf
wrappers, qdf_runtime_pm_get and qdf_runtime_pm_put are
introduced.

For some 3rd party platforms, get_timestamp through legacy
kernel API is time costing. For spin_lock/unlock statistics
info, the resolution in ms level is enough. So use another
light weight API to save CPU resource for 3rd party
platforms only.

During system suspending, the target might request wakeup early to the
host. The host will wakeup the system directly to abort current suspend
to avoid mismatching PM state between host & target.

Move all qdf_print from printk to qdf_trace_msg so that trace level
management can be carried out at runtime
In addition to the above, change contains removal of newline
escape characters from the format string of the converged
print APIs since qdf_trace_msg appends them by default.

Runtime PM lock init API right now returns pointer to a context
but this would cause confusion to the caller if feature is not
defined and dummy function return NULL as caller can't find real
failure versus dummy function returning because feature not being
enabled.
Fix declaring a data structure in QDF layer that caller can use
but it hides the internal details of HIF implementation for
Runtime PM locks.

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.
