Subject: [PATCH v2] PCI: imx6: Support building it as a module
Change config from bool to tristate and add MODULE_LICENSE to support
building pci-imx6 as a module.
Also export dw_pcie_ep_raise_msix_irq() to fix build error when
CONFIG_PCIE_DW_EP=y is set:
ERROR: modpost: "dw_pcie_ep_raise_msix_irq"
[drivers/pci/controller/dwc/pci-imx6.ko] undefined!
This error was found by kernel test robot <lkp@...el.com>.

v1 -> v2:
Export dw_pcie_ep_raise_msix_irq to fix build error
