[RFC PATCH] net: phy: Don't miss phy_suspend() on PHY_HALTED for PHYs with interrupts

[Roger Quadros]

Since commit 3c293f4e08b5 ("net: phy: Trigger state machine on state change and not polling.")
phy_suspend() doesn't get called as part of phy_stop() for PHYs using
interrupts because the phy state machine is never triggered after a phy_stop().

Explicitly trigger the PHY state machine so that it can
see the new PHY state (HALTED) and suspend the PHY.
