Cosmin Tanislav 6d0473b442 regmap: detach regmap from dev on regmap_exit ...

commit 3061e170381af96d1e66799d34264e6414d428a7 upstream.

At the end of __regmap_init(), if dev is not NULL, regmap_attach_dev()
is called, which adds a devres reference to the regmap, to be able to
retrieve a dev's regmap by name using dev_get_regmap().

When calling regmap_exit, the opposite does not happen, and the
reference is kept until the dev is detached.

Add a regmap_detach_dev() function and call it in regmap_exit() to make
sure that the devres reference is not kept.
