bcm53xx: add support for the PCIe controller

This patch adds support for the PCIe controller
In addition to the PCIe controller a sprom is now provided by a device
tree driver to bcma from some nvram.

+Subject: [PATCH 02/15] bcm47xx: move the nvram header file into common space
+
+Moving mach-bcm47xx/bcm47xx_nvram.h makes it possible to reuse this
+header on the arm bcm47xx (BCM5301X) devices. This way a driver gets
+the correct functions to access the nvram depending on the SoC it boots
+for.
