Subject: [PATCH] regulator: da9063: Return an error code on probe failure

If "regl_pdata->n_regulators == 0" is true then we accidentally return
PTR_ERR(<some_valid_pointer>) instead of an error code.  I've changed it
to return -ENODEV instead.

Fixes: 69ca3e58d178 ("regulator: da9063: Add Dialog DA9063 voltage regulators support.")
