kernel/resource: simplify API __devm_release_region() implementation

Simplify __devm_release_region() implementation by dedicated API
devres_release() which have below advantages than current
__release_region() + devres_destroy():

It is simpler if __devm_release_region() is undoing what
__devm_request_region() did, otherwise, it can avoid wrong and undesired
__release_region().
