HID: bpf: drop use of Logical|Physical|UsageRange

Browse Source 
Replace with individual Minimum/Maximum calls to match the HID report
descriptor - HID doesn't have a Range field. Abstracting this is good
for hand-written descriptors but almost all tools will output min/max
instead so let's stick with that.
