mb/prodrive/atlas: Enable/disable sleep states based on EC 

With the profile ATLAS_PROF_REALTIME_PERFORMANCE it is desired to not
have the option to be able to enter sleep. The reason is that Microsoft
Windows goes to sleep after 30min of inactivity by default.

TEST: See that Microsoft Windows 11 has no 'Sleep' option in the start
menu.
