Currently enabling PCI_EXP_RTSTA_PME bit in PCI_EXP_RTCTL register does nothing. This is because PCIe PME driver expects to receive PCIe interrupt defined in PCI_EXP_FLAGS_IRQ register, but aardvark hardware does not trigger PCIe INTx/MSI interrupt for PME event, rather it triggers custom aardvark interrupt which this driver is not processing yet. Fix this issue by handling PME interrupt in advk_pcie_handle_int() and chaining it to PCIe interrupt 0 with generic_handle_domain_irq() (since aardvark sets PCI_EXP_FLAGS_IRQ to zero). With this change PCIe PME driver finally starts receiving PME interrupt.
