smsc75xx: Check for Wake-on-LAN modes

Browse Source 
[ Upstream commit 9c734b2769a73eea2e9e9767c0e0bf839ff23679 ]

The driver does not check for Wake-on-LAN modes specified by an user,
but will conditionally set the device as wake-up enabled or not based on
that, which could be a very confusing user experience.
