HID: fix broken Logitech S510 keyboard report descriptor; make extra keys work
This patch makes extra keys (F1-F12 in special mode, zooming, rotate, shuffle)
on Logitech S510 keyboard work.
Logitech S510 keyboard sends in report no. 3 keys which are far above the
logical maximum described in descriptor for given report.
This patch introduces a HID quirk for this wireless USB receiver/keyboard
in order to fix the report descriptor before it's being parsed - the logical
maximum and the number of usages is bumped up to 0x104d). The values are in the
"Reserved" area of consumer HUT, so HID_MAX_USAGE had to be changed too.
In addition to proper extracting of the values from report descriptor, proper
HID-input mapping is introduced for them.
