Enabling a (modular) test should not silently enable additional kernel
functionality, as that may increase the attack vector of a product.
Fix this by:
1. making REGMAP visible if CONFIG_KUNIT_ALL_TESTS is enabled,
2. making REGMAP_KUNIT depend on REGMAP instead of selecting it.
After this, one can safely enable CONFIG_KUNIT_ALL_TESTS=m to build
modules for all appropriate tests for ones system, without pulling in
extra unwanted functionality, while still allowing a tester to manually
enable REGMAP and its test suite on a system where REGMAP is not enabled
by default.

Enable support for the Register Map (regmap) access API.

Usually, this option is automatically selected when needed.

However, you may want to enable it manually for running the regmap

KUnit tests.

If unsure, say N.
