[Arista] Enable interrupts on all cores

[arista-nwolfe]

We noticed that starting in SAI14 the interrupt enable id= command would only enable the interrupt on core=0:

bcmcmd -n 0 'show interrupt all' | grep 1597
=================================================================================================================
|                                                              Interrupt                                        |
=================================================================================================================
| Interrupt Name#                                                          | ID   | UnMask(Enable) | On | Count |
=================================================================================================================
| IPS_QueueEnteredDel[0]                                                   | 1597 | 1              | 0  | 0       |
| IPS_QueueEnteredDel[1]                                                   | 1597 | 0              | 0  | 0       |

If we add p=<core> to the command it enables it on the core.

On SAI13 the same command would enable interrupts on all cores

bcmcmd -n 0 'show interrupt all' | grep 1597
=================================================================================================================
|                                                              Interrupt                                        |
=================================================================================================================
| Interrupt Name#                                                          | ID   | UnMask(Enable) | On | Count |
=================================================================================================================
| IPS_QueueEnteredDel[0]                                                   | 1597 | 1              | 0  | 0       |
| IPS_QueueEnteredDel[1]                                                   | 1597 | 1              | 0  | 0       |

I've opened CS00012451517 to check with BRCM if this is intentional or a regression.
But regardless if it's a regression it may take a while for a fix from BRCM to be integrated upstream so posting this change to update the interrupts on Arista SKUs
