[PATCH] regmap: add regmap_debugfs_exit as devres action

[Stefan Agner]

Instead of manually cleanup regmap_debugfs_exit, use devres action
to do the cleanup. This also works for external users of
regmap_attach_dev.

The cast is not that pretty, but I found it better than making
regmap_debugfs_exit type unsafe...

This fixes warnings when reloading certain drivers making use of
regmap_debugfs_exit:
  imx7d-pinctrl 30330000.iomuxc: Failed to create debugfs directory
