[PATCH v1 1/2] phy: qcom: qmp-combo: Add PM suspend/resume callbacks

[Prashanth K]

Currently when we perform system suspend, the phy clocks aren't
turned off leading to power leakage. Prevent this by adding PM
suspend/resume callbacks for the qmp-combo-phy which toggles
clocks on/off correspondingly.
