On ACPI based systems the CPLM3218 ACPI device node describing the
CM3218[1] sensor typically will have some extra tables with register
init values for initializing the sensor and calibration info.
This is based on a newer version of cm32181.c, with a copyright of:

Which is floating around on the net in various places, but the changes
from this newer version never made it upstream.
This was tested on the following models: Acer Switch 10 SW5-012 (CM32181)
Asus T100TA (CM3218), Asus T100CHI (CM3218) and HP X2 10-n000nd (CM32181).
