msm: pcie: update with link power on check for user PCIe resume 



Instead of checking PCIe S/W link state, check if the link is on
is on or off to determine whether PCIe resume should be allowed
or not. PCIe S/W link state is not enough to determine since
MSM_PCIE_LINK_DOWN state can be set for link on or off.
