nss-drv: rework smp affinity hangling

Browse Source 
Reworked SMP affinity handling for better balancing of PPDU and USBs

```
Pinning IRQ(46) nss_queue0               to CPU 0 (NSS Core 0)
Pinning IRQ(47) nss_queue1               to CPU 1 (NSS Core 0)
Pinning IRQ(48) nss_queue2               to CPU 2 (NSS Core 0)
Pinning IRQ(49) nss_queue3               to CPU 3 (NSS Core 0)
Pinning IRQ(57) nss_queue0               to CPU 3 (NSS Core 1)
Pinning IRQ(58) nss_queue1               to CPU 2 (NSS Core 1)
Pinning IRQ(59) nss_queue2               to CPU 1 (NSS Core 1)
Pinning IRQ(60) nss_queue3               to CPU 0 (NSS Core 1)
Pinning IRQ(43) nss_empty_buf_sos        to CPU 0 (NSS Core 0)
Pinning IRQ(44) nss_empty_buf_queue      to CPU 0 (NSS Core 0)
Pinning IRQ(53) nss_empty_buf_sos        to CPU 3 (NSS Core 1)
Pinning IRQ(55) nss_empty_buf_queue      to CPU 3 (NSS Core 1)
Pinning IRQ(41) xhci-hcd:usb1            to CPU 2
Pinning IRQ(42) xhci-hcd:usb3            to CPU 2
Pinning IRQ(79) ppdu-end-interrupts-mac1 to CPU 2
Pinning IRQ(83) ppdu-end-interrupts-mac2 to CPU 3
Pinning IRQ(81) ppdu-end-interrupts-mac3 to CPU 1
```

Primarily meant to improve performance on Arcadyan AW1000 which uses USB
based cellular modems (xhci-hcd:usb3). They are now pinned to CPU 2
