hid: topre: Add driver fixing report descriptor
The Topre REALFORCE R2 firmware incorrectly reports that interface
descriptor number 1, input report descriptor 2's events are array events
rather than variable events. That particular report descriptor is used
to report keypresses when there are more than 6 keys held at a time.
This bug prevents events from this interface from being registered
properly, so only 6 keypresses (from a different interface) can be
registered at once, rather than full n-key rollover.
This commit fixes the bug by setting the correct value in a report_fixup
function.
The original bug report can be found here:

Thanks to Benjamin Tissoires for diagnosing the issue with the report
descriptor.
