[PATCH V8 6/9] SPEAr13XX: Add binding information for PCIe controller

[Mohit Kumar <mohit.kumar-qxv4g6HH51o@public.gmane.org>]

From: Pratyush Anand <pratyush.anand-qxv4g6HH51o@public.gmane.org>

SPEAr13XX uses designware PCIe controller. This patch adds information
for the PCIe binding properties which are specific to SPEAr13XX SoC
series.

+SPEAr13XX PCIe DT detail:
+================================
+
+SPEAr13XX uses synopsis designware PCIe controller and ST MiPHY as phy
+controller.
+
+Required properties:
+- compatible : should be "st,spear1340-pcie", "snps,dw-pcie".
+- phys		    : phandle to phy node associated with pcie controller
+- phy-names	    : must be "pcie-phy"
+- All other definitions as per generic PCI bindings
+
+ Optional properties:
+- st,pcie-is-gen1 indicates that forced gen1 initialization is needed.
