regulator: spm-regulator: check spm status in probe function



Check the status of the spm driver using msm_spm_probe_done()
inside of the spm-regulator probe function.  Return any error
code from the probe function.  This ensures that spm-regulator
will defer its probe in the case that the spm driver has not
yet probed.
