For debugging many issues, a history of the

driver is run in debug mode (i.e. with the
config ATH10K_DEBUG enabled).

This should be disabled by default unless user specifically pokes some debugfs
value to turn it on so that it does not impact performance.

Thanks,

Add history for tracking the below events
- register read
- register write
- IRQ trigger
- IRQ Enable
- IRQ Disable
- NAPI poll
- CE service
- WMI cmd
- WMI event
- WMI tx completion

This will help in debugging any crash or any
improper behaviour.
