qcacmn: Add support for rate limiting QDF trace prints

The existing QDF implementation does the following
1. The QDF trace either prints to the console
2. The QDF trace message  is directed to the utils,
   which based on log level
	a. redirects to a user space daemon or
	b. redirects to console

There is excessive logging detection in the utils code
before redirecting the prints to  the console.
If the number of prints to console is more than
the configured threshold, we assert in development builds.

Moving the API for excessive logging detection from utils to
QDF trace.

The configuration for detection of excessive logging currently
is only for the number of prints per second.
Adding time configuration also to detection of excess logging
to the console.
