HID: bpf: Add Huion Dial 2 bpf fixup

Pretty much similar to the Inspiroy 2, but with 2 wheels and 8 buttons.

This bpf also works in both normal and vendor mode. If the device is
switched into vendor mode by huion-switcher, a udev property is set
which is then retrieved by this bpf object. This allows to hide the now
unused normal collections.
