On a setup with KSZ9131 and MACB drivers it happens on suspend path, from
time to time, that the PHY interrupt arrives after PHY and MACB were
suspended (PHY via genphy_suspend(), MACB via macb_suspend()). In this
case the phy_read() at the beginning of kszphy_handle_interrupt() will
fail (as MACB driver is suspended at this time) leading to phy_error()
being called and a stack trace being displayed on console. To solve this
.suspend/.resume functions for all KSZ devices implementing
.handle_interrupt were replaced with kszphy_suspend()/kszphy_resume()
which disable/enable interrupt before/after calling
genphy_suspend()/genphy_resume().
The fix has been adapted for all KSZ devices which implements
.handle_interrupt but it has been tested only on KSZ9131.
