This patch adds necessary DT nodes for pcie controllers and miphys for SPEAr13xx SoCs. SPEAr1310 has 3 PCIe ports and SPEAr1340 has 1, which are multiplexed with ahci/sata pins. By default evaluation board of both controller works in ahci mode. Because of this, these nodes are marked "disabled" by default. In order to use pcie controller on evaluation boards do necessary modifications on board and enable (By replacing "disabled" with "okay") pcie and miphy from respective 'evb' dtsi file. Phy specific initialization was previously done from spear1340.c, which isn't required anymore as we have separate drivers for it. Remove it.
