HID: logitech: add Bolt receiver support for Logitech HID++ devices

Browse source

Add Logitech Bolt receiver support to the Logitech HID receiver and
HID++ drivers.

Handle Bolt receiver notifications in hid-logitech-dj and add a
Bolt-specific initialization path in hid-logitech-hidpp, separate from
the existing Unifying receiver path.

This allows Bolt-connected HID++ devices to expose battery information
through the kernel power_supply path, so userspace tools can report
their battery status with the correct device model.

Also, treat HIDPP_ERROR_CONNECT_FAIL like other disconnected-device
errors when retrieving protocol version to avoid protocol error messages
when a Bolt device powers off.

Tested with:
- Logitech MX Keys for Business via Bolt receiver
