Although the XPS 9360 and XPS 9365 are currently the only Dell products on
the market that do the wakeup this way, this is part of Dell's BIOS and EC
codebase.  As other Dell products start to ship Windows 10 with Modern Standby
and (eventually) Linux with Suspend-to-Idle I'd expect this list to be growing.

Well, if init_ec_gpe_wakeup() was enabled on all Dell systems at this
point, it would affect all previous generations of them too and that
might not be desirable.

Thanks,
