[PATCH v1 0/5] Add Keystone PCIe controller driver

This patch adds a PCIe controller driver for Keystone SoCs. This
is based on the origin RFC patch that I had sent earlier. I have
incorporated following comments:-

- Add a interrupt controller node for Legacy irq chip and use
interrupt map/map-mask property to map legacy IRQs A/B/C/D
- Add a Phy driver to replace the original serdes driver
- Move common applicaiton register handling code to a separate
file to allow re-use across other platforms that use older
DW PCIe h/w
- PCI quirk for maximum read request size. Check and override only
if the maximum is higher than what controller can handle.
- Converted to a module platform driver.
