If devm_add_action() fails we are explicitly calling
axp20x_remove_sysfs_group() to free the resources allocated. Lets use
the helper devm_add_action_or_reset() and return directly in case of
error, as we know that the cleanup function has been already called by
the helper if there was any error.

Hmm, I need to try and get Greg accept my devm_add_sysfs_group(), if
that fails I'll take this patch.
Thanks.
