[PATCH-next] net: ethernet: mediatek: fix implicit irq include causing build fails

[Paul Gortmaker]

To fix:

drivers/net/ethernet/mediatek/mtk_eth_soc.c:1685:1: error: unknown type name 'irqreturn_t'
drivers/net/ethernet/mediatek/mtk_eth_soc.c: In function 'mtk_handle_irq_rx':
drivers/net/ethernet/mediatek/mtk_eth_soc.c:1694:9: error: 'IRQ_HANDLED' undeclared (first use in this function)
drivers/net/ethernet/mediatek/mtk_eth_soc.c:1694:9: note: each undeclared identifier is reported only once for each function it appears in

and similar follow-on errors as seen in arm allmodconfig builds.

[Seen on current linux-next, where similar implicit irq includes
 were recently revealed by some header shuffle somewhere.]
