HID: add support for Skycable 0x3f07 wireless presenter 



This device contains the very same bug in report descriptor as the
Ortek ones do (i.e. LogicalMinimum == 1, which is wrong for the key
array).

As we have more reports for the Ortek devices, we are keeping the driver
name for now. Apparently there is a chip producer which sells chip with
this buggy descriptor to multiple vendors. Thus if such reports start
to come at highger frequency, we'll either have to rename the driver
accordingly, or come up with more generic workaround.
