net: bcmgenet: synchronize irq0 status between the isr and task
Add a spinlock to ensure that irq0_stat is not unintentionally altered
as the result of preemption. Also removed unserviced irq0 interrupts
and removed irq1_stat since there is no bottom half service for those
interrupts.
Fixes: 1c1008c793fa ("net: bcmgenet: add main driver file")
