qcacmn: Add INI to disable wake IRQ

Browse Source 
Some platform would like to disable wake IRQ, so add INI to disable
wake IRQ.

Wake IRQ can't share the same IRQ with the copy engines. In one MSI
mode, we don't know whether wake IRQ is triggered or not in wake IRQ
handler. known issue CR 2055359.

Disable wake IRQ for one MSI mode. If you want to support wake IRQ.
Please allocate at least 2 MSI vector. The first is for wake IRQ while
the others share the second vector.
