Subject: [PATCH v2 1/3] PCI: qcom: Add sc7280 aggre0, aggre1 and ddr sf tbu clocks in PCIe driver

Add missing aggre0, aggre1 and ddrs sf tbu clocks in PCIe driver.

If these clocks are not voted-on, then PCIe link is going down when system
is suspended as these clocks can get turned off.

And these clocks are needed only on sc7280 target.
