regmap: kunit: Run non-sparse cache tests at non-zero register addresses 

Change the tests parameterized by real_cache_types_list[] to test at some
register addresses that are not 0.

The cache_range_window_reg() test has hardcoded address assumptions that
are not present in any other tests using real_cache_types_list[] table. So
it has been given a separate parameter table, real_cache_types_only_list[],
that preserves the original parameterization.
