net: phy: cicada: implement the generic .handle_interrupt() callback
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. Signed-off-by: Ioana Ciornei <ioana.ciornei@nxp.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
