Certain ACPI based tablets with e.g. Silead or Chipone touchscreens
do not have enough data in ACPI tables for the touchscreen driver to
handle the touchscreen properly, as OEMs expect the data to be baked
into the tablet model specific version of the driver shipped with the
the OS-image for the device. This option supplies the missing info.
Enable this for x86 tablets with Silead or Chipone touchscreens.
