HID: support for Petalynx Maxter remote control
Petalynx Maxter remote control [1] 0x18b1/0x0037 emits 0xfa and 0xfc from
consumer page (reserved in HUT 1.12) for back and more keys. It also emits
a few usages from LOGIVENDOR page, which need adding.
Also, this device has broken report descriptor - the reported maximum is too
low - it doesn't contain the range for 'back' and 'more' keys, so we need to
bump it up before the report descriptor is being parsed.
Besides all this, it also requires NOGET quirk.
This patch does so.
