Use units of 1/100000th for calibscale and lux_per_bit. The similar cm3232 driver already uses 1/100000th as unit for calibscale. This allows for higher-accuracy and makes it easier to add support for getting device-specific calibscale and lux_per_bit values from a device's ACPI tables, as the values in the ACPI tables also use 1/100000th units. This units change means that our intermediate values in cm32181_get_lux() may get quite big, change the type of the lux variable to a u64 to deal with this.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
