platform/x86: touchscreen_dmi: Update info for the Chuwi Hi10 Plus (CWI527) tablet
[ Upstream commit 196159d278ae3b49e7bbb7c76822e6008fd89b97 ]
Add info for getting the firmware directly from the UEFI for the Chuwi Hi10
Plus (CWI527), 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.
Also tweak the min and width/height values a bit for more accurate position
reporting.
