The Keystone PCIe controller is based on v3.65 version of the Designware
h/w. Main differences are:
1. No ATU support
2. Legacy and MSI IRQ functions are implemented in application register
space
3. MSI interrupts are multiplexed over 8 IRQ lines to the Host side.
All of the application register space handing code is organized into
pci-keystone-dw.c and the functions are called from pci-keystone.c to
implement PCI controller driver. Also add necessary DT documentation and
update the MAINTAINERS file for the driver.
