Revert "PCI: qcom: Enable MSI interrupts together with Link up if 'Global IRQ' is supported"
[ Upstream commit 7ebdefb87942073679e56cfbc5a72e8fc5441bfc ]
This reverts commit ba4a2e2317b9faeca9193ed6d3193ddc3cf2aba3.
Since the Link up IRQ support is going away, revert the MSI logic that got
added for it too.
