net: txgbe: use irq_domain for interrupt controller

In the current interrupt controller, the MAC interrupt acts as the
parent interrupt in the GPIO IRQ chip. But when the number of Rx/Tx
ring changes, the PCI IRQ vector needs to be reallocated. Then this
interrupt controller would be corrupted. So use irq_domain structure
to avoid the above problem.

net: wangxun: add ethtool_ops for channel number

Add support to get RX/TX queue number with ethtool -l, and set RX/TX
queue number with ethtool -L. Since interrupts need to be rescheduled,
adjust the allocation of msix enties.
