Input: add Himax HX852x(ES) touchscreen driver
Add a simple driver for the Himax HX852x(ES) touch panel controller,
with support for multi-touch and capacitive touch keys.
The driver is somewhat based on sample code from Himax. However, that
code was rather confusing, so that we spent a significant amount of
time just trying to understand the packet format and register commands.
In this driver they are described with clean structs and defines rather
than magic numbers and offset calculations.
