[PATCH] HID: logitech-hidpp: Enable MX Master 4 over bluetooth

[Adrian Freund <adrian@freund.io>]

The Logitech MX Master 4 can be connected over bluetooth or through a
Logitech Bolt receiver. This change adds support for non-standard HID
features, such as high resolution scrolling when the mouse is connected
over bluetooth.
Because no Logitech Bolt receiver driver exists yet those features
won't be available when the mouse is connected through the receiver.
