regmap: Disable locking for RBTREE and MAPLE unit tests
REGCACHE_RBTREE and REGCACHE_MAPLE dynamically allocate memory
for regmap operations. This is incompatible with spinlock based locking
which is used for fast_io operations. Disable locking for the associated
unit tests to avoid lockdep splashes.
Fixes: f033c26de5a5 ("regmap: Add maple tree based register cache")
Fixes: 2238959b6ad2 ("regmap: Add some basic kunit tests")
