platform/x86: touchscreen_dmi: Add info for the Chuwi Hi10 Pro (CWI529) tablet

[ Upstream commit e68671e9e1275dfdda333c3e83b6d28963af16b6 ]

Add touchscreen info for the Chuwi Hi10 Pro (CWI529) tablet. This includes
info for getting the firmware directly from the UEFI, so that the user does
not need to manually install the firmware in /lib/firmware/silead.

This change will make the touchscreen on these devices work OOTB,
without requiring any manual setup.
