QCM6490 uses Trustzone as firmware whereas SC7280 uses arm trusted
firmware. The PSCI suspend param is different in Trustzone for cluster
sleep. Update the same for qcm6490 based idp and fairphone fp5 boards.

Thanks for the review.
Moved the chrome specific changes to sc7280-chrome-common.dtsi in v2.
