qcacmn: Register IRQ for near full irq

Browse Source 
WCN7850 has support for near full indication for
the consumer srngs. This interrupt is used to take
preventive actions to avoid ring full watchdog irq
trigger.

Register for the near full irq and add the necessary
ext groups for these near-full irqs.
