qcacmn: Add support to populate and send UMAC reset setup command

UMAC reset prerequisite setup command contains the following information.
- Interrupt number to be used for raising the UMAC reset interrupt
- Address of the shared memory
This is an HTT command. Send this command as part of the UMAC reset
initialization sequence.
