On some platforms (for example, QCx6490), XO (Crystal Oscillator) shutdown

iw phy0 wowlan enable magic-packet
Add an udev rule to automatically enable WoWLAN magic-packet support when
a Wi-Fi PHY is registered. This rule is provided via a dedicated
wowlan-udev package and is not enabled by default.
Integrators should include this package only if their platform requires
automatic WoWLAN magic-packet enablement.

Since it's just a single file copy, adding INHIBIT_DEFAULT_DEPS = "1"
could save a few file copy calls during build.
Thanks, will update in v2.
