[ Upstream commit 5a3c680aa2c12c90c44af383fe6882a39875ab81 ]
Setting the EXT_ENERGY_DET_MASK bit allows the port energy detection logic of the internal PHY to prevent the system from sleeping. Some internal PHYs will report that energy is detected when the network interface is closed which can prevent the system from going to sleep if WoL is enabled when the interface is brought down.
Since the driver does not support waking the system on this logic, this commit clears the bit whenever the internal PHY is powered up and the other logic for manipulating the bit is removed since it serves no useful function.
