HID: uhid: report to user-space whether reports are numbered
This makes UHID_START include a "dev_flags" field that describes details of the hid-device in the kernel. The first flags we introduce describe whether a given report-type uses numbered reports. This is useful for transport layers that force report-numbers and therefore might have to prefix kernel-provided HID-messages with the report-number. Currently, only HoG needs this and the spec only talks about "global report numbers". That is, it's a global boolean not a per-type boolean. However, given the quirks we already have in kernel-space, a per-type value seems much more appropriate.
