[ Upstream commit 7725363936a88351b71495774c1e0e852ae4cdca ]
When Wake-on-LAN (WoL) is active and the system is in suspend mode, triggering
a system event can wake the system from sleep, which may block the data path.
To restore normal data path functionality after waking, disable all wake-up
events. Furthermore, clear all Write 1 to Clear (W1C) status bits by writing
1's to them.
Fixes: 4d94282afd95 ("lan743x: Add power management support")
