qcacmn: Changes to converge WMI Recording feature

Browse Source 
1.Logging of all WMI activities(commands, tx complete, events)
is adapted for WIN.
2. WIN and MCL continues to use existing approach of memory
allocation and it is managed using feature flag in common code.
3. Use debugfs for WMI event debugging.

example to read buffer through debugfs interface -
- Navigate to WMI directory under debugfs (/sys/kernel/debug/WMIx)
- It will display elements/files for all command/event buffers
- "cat wmi_command_log" (desired buffer name)
- Output will display something like this:
CMD ID = 16001
CMD = d 0 d8c6de24 e1cf
CMD ID = 16001
CMD = 8 0 0 0
CMD ID = 16001
CMD = d 0 d8c6de24 e1cf
CMD ID = 16001
