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

Run the cache_drop() and cache_present() tests at blocks of addresses
that don't start at zero.

This adds a from_reg parameter to struct regmap_test_param. This is
used to set the base address of the register defaults created by
gen_regmap().

Extra entries are added to sparse_cache_types_list[] to test at non-zero
from_reg values. The cache_drop() and cache_present() tests are updated
to test at the given offset.

The aim here is to add test cases to cache_drop() for the bug fixed by
commit 00bb549d7d63 ("regmap: maple: Fix cache corruption in
regcache_maple_drop()")

But the same parameter table is used by the cache_present() test so
let's also update that to use from_reg.
