qca-nss-drv: add affinity function to set last match

Browse Source 
Since NSS IRQs use the same name for each core, the current function
assigns all matching names to the same CPU core. Add function
'set_affinity_last' to specify that only the 'last' matching irq ID be set
to the specified CPU core.
