HID: add HID_QUIRK_HIDDEV_FORCE and HID_QUIRK_NO_IGNORE
Add two quirks to make it possible for usbhid module options to
override whether a device is ignored (HID_QUIRK_NO_IGNORE) and
whether to connect a hiddev device (HID_QUIRK_HIDDEV_FORCE).
Passing HID_QUIRK_NO_IGNORE for your device means that it will
not be ignored by the HID layer, even if present in a blacklist.
HID_QUIRK_HIDDEV_FORCE will force the creation of a hiddev for that
device, making it accessible from user-space.
Tested with an Apple IR Receiver, switching it from using appleir
to using lirc's macmini driver.
