PCI: qcom: Don't deassert reset GPIO during probe [ Upstream commit 02b485e31d98265189b91f3e69c43df2ed50610c ] Acquiring the reset GPIO low means that reset is being deasserted, this is followed almost immediately with qcom_pcie_host_init() asserting it, initializing it and then finally deasserting it again, for the link to come up. Some PCIe devices requires a minimum time between the initial deassert and subsequent reset cycles. In a platform that boots with the reset GPIO asserted this requirement is being violated by this deassert/assert pulse. Acquire the reset GPIO high to prevent this situation by matching the state to the subsequent asserted state.
