Some weird remotes are not correctly creating the input device. Their
report descriptor starts with:
0x06, 0x00, 0xff,              // Usage Page (Vendor Defined Page 1)  0
0xa1, 0x01,                    // Collection (Application)            3

whereas others (which are correctly handled) start with:
0x05, 0x0c,                    // Usage Page (Consumer Devices)       0
0x09, 0x01,                    // Usage (Consumer Control)            2
0xa1, 0x01,                    // Collection (Application)            4

The rest of the report descriptor is the same.

Adding the quirk HID_QUIRK_HIDINPUT_FORCE forces hid-input to allocate
the inputs, and everything should be ok.
