Subject: [PATCH] regmap: REGMAP_KUNIT must not select REGMAP

Enabling a (modular) test must not silently enable additional kernel
functionality, as that may increase the attack vector of a product.

Fix this by making REGMAP_KUNIT depend on REGMAP instead.

Fixes: 2238959b6ad27040 ("regmap: Add some basic kunit tests")
