net: phy: ti: take into account all possible interrupt sources
[ Upstream commit 73f476a ] The previous implementation of .handle_interrupt() did not take into account the fact that all the interrupt status registers should be acknowledged since multiple interrupt sources could be asserted. Fix this by reading all the status registers before exiting with IRQ_NONE or triggering the PHY state machine.
