regmap: kunit: Add a test for ranges in combination with windows

Browse Source 
In preparation for taking advantage of the SPI support for pre-coooked
messages add a test case covering the use of windows on a raw regmap,
unfortunately the parameterisation prevents direct reuse and we will
want to add some raw specific coverage anyway.
