net: ll_temac: Allow configuration of IRQ coalescing
This allows custom setup of IRQ coalescing for platforms using legacy
platform_device. The irq timeout and count parameters can be used for
tuning cpu load vs. latency.
I have maintained the 0x00000400 bit in TX_CHNL_CTRL. It is specified as
unused in the documentation I have available. It does not make any
difference in the hardware I have available, so it is left in to not risk
breaking other platforms where it might be used.
