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.

Support for Ortek PKB-1700/WKB-2000 wireless keyboard + mouse trackpad.
There are certain devices which have LogicalMaximum wrong in the keyboard
usage page of their report descriptor. The most prevailing ones so far
are manufactured by Ortek, thus the name of the driver. Currently
supported devices by this driver are
- Ortek PKB-1700
- Ortek WKB-2000
- Skycable wireless presenter
