PCI: dwc: Export DWC MSI controller related APIs
Export dw_pcie_msi_host_init(), dw_pcie_msi_init(), and dw_pcie_free_msi()
APIs to allow them to be reused by the upcoming DWC based ECAM driver
implementation. Also, move MSI IRQ related initialization code to
dw_pcie_msi_init(), as this code must be executed before dw_pcie_msi_init()
API can be used with ECAM driver.
