qcacmn: Enhance ce register dump and add hif_get_irq_num

Modify the CE register debug dump routine to print the read,
write indexes on the console.

Add new function  to return vector used for specific radio.
WIN uses this routine to retrieve the irq and assign the same
to radio netdev irq field. Assign the radio netdev with
the right irq number which helps qrfs to steer to traffic
towards a specific core.
