regmap: Remove debugfs before cache teardown
regmap_exit() and regmap_reinit_cache() destroy the register cache before
removing debugfs. A concurrent debugfs cache operation can therefore
access cache state after the backend exit callback starts freeing it.
Remove debugfs before cache teardown, and clear the debugfs pointer after
removal. During cache reinitialization, recreate debugfs only after the
new cache initializes successfully.
