Subject: [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.
