PCI: qcom: Skip DWC MSI host initialization when DT 'msi-map' is present
qcom_pcie_ecam_host_init() unconditionally initializes the DesignWare
internal MSI controller and sets use_imsi_rx, irrespective of whether an
external MSI controller is described for the host bridge. When an 'msi-map'
DT property is present, MSI interrupts are handled by the mapped external
MSI controller. Initializing the internal iMSI-RX domain in this case is
unnecessary.
Set use_imsi_rx based on the presence of 'msi-map' in DT and initialize the
DesignWare MSI host only when iMSI-RX is required.
