[PATCH RESEND net-next 15/18] net: phy: ste10Xp: implement generic .handle_interrupt() callback

[Ioana Ciornei]

From: Ioana Ciornei <ioana.cior...@nxp.com>

In an attempt to actually support shared IRQs in phylib, we now move the
responsibility of triggering the phylib state machine or just returning
IRQ_NONE, based on the IRQ status register, to the PHY driver. Having
3 different IRQ handling callbacks (.handle_interrupt(),
.did_interrupt() and .ack_interrupt() ) is confusing so let the PHY
driver implement directly an IRQ handler like any other device driver.
Make this driver follow the new convention.
