[PATCH BlueZ 0/3] Hide WakeAllowed when the adapter cannot wake the host

The WakeAllowed property is currently exposed on any device whose
profile supports wake configuration (HID/HoG), regardless of whether
the host controller is configured to wake the system. Clients may decide
whether to offer a "wake the system by this device" toggle based on the
presence of this property, and end up offering it on hardware where it
won't work.

This series gates the property's existence on the adapter's current
wakeup configuration, read from the power/wakeup attribute of the
closest USB ancestor in sysfs. That is the same attribute btusb
consults through device_may_wakeup() on the underlying USB device,
and hci_suspend_sync() skips wakeup configuration entirely when that
callback returns false. Only the USB case is handled, so controllers
on other buses keep the current behavior.
