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.
