net: airoha: Enable multiple IRQ lines support in airoha_eth driver.

Browse source

EN7581 ethernet SoC supports 4 programmable IRQ lines for Tx and Rx
interrupts. Enable multiple IRQ lines support. Map Rx/Tx queues to the
available IRQ lines using the default scheme used in the vendor SDK:

- IRQ0: rx queues [0-4],[7-9],15
- IRQ1: rx queues [21-30]
- IRQ2: rx queues 5
- IRQ3: rx queues 6

Tx queues interrupts are managed by IRQ0.
