platform/x86: touchscreen_dmi: Add info for the Chuwi HiBook (CWI514) tablet

[ Upstream commit 3bf1669b0e033c885ebcb1ddc2334088dd125f2d ]

Add touchscreen info for the Chuwi HiBook (CWI514) 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.
