[ Upstream commit e917b73234b02aa4966325e7380d2559bf127ba9 ]
Only go into the if condition for single-PD handling when there's actually just one power domain specified there. Otherwise it'll be an issue in the dts and we should fail in the regular code path.
This also mirrors the latest changes in the qcom_q6v5_mss driver.
