HID: multitouch: Add quirk for HONOR GLO-GXXX touchpad
Honor MagicBook 13 2023 has a touchpad which do not switch to the multitouch mode until the input mode feature is written by the host. The touchpad do report the input mode at touchpad(3), while itself working under mouse mode. As a workaround, it is possible to call MT_QUIRE_FORCE_GET_FEATURE to force set feature in mt_set_input_mode for such device. The touchpad reports as BLTP7853, which cannot retrive any useful manufacture information on the internel by this string at present. As the serial number of the laptop is GLO-G52, while DMI info reports the laptop serial number as GLO-GXXX, this workaround should applied to all models which has the GLO-GXXX.
