Add code needed to get a functional PCI subsytem when using in
conjunction with upstream Linux guest (4.13+). Tested to work against
"e1000e" (network adapter, using MSI interrupts) as well as
"usb-ehci" (USB controller, using legacy PCI interrupts).
Based on "i.MX6 Applications Processor Reference Manual" (Document
Number: IMX6DQRM Rev. 4) as well as corresponding dirver in Linux
kernel (circa 4.13 - 4.16 found in drivers/pci/dwc/*)

The following interfaces are partially or fully emulated:
* up to 2 Cortex A9 cores (SMP works with PSCI)
* A7 MPCORE (identical to A15 MPCORE)
* 4 GPTs modules
* 7 GPIO controllers
* 2 IOMUXC controllers
* 1 CCM module
* 1 SVNS module
* 1 SRC module
* 1 GPCv2 controller
* 4 eCSPI controllers
* 4 I2C controllers
* 7 i.MX UART controllers
* 2 FlexCAN controllers
* 2 Ethernet controllers (FEC)
* 3 SD controllers (USDHC)
* 4 WDT modules
* 1 SDMA module
* 1 GPR module
* 2 USBMISC modules
* 2 ADC modules
* 1 PCIe controller
Tested to boot and work with upstream Linux (4.13+) guest.
