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 04/15] bcm53xx-sprom: add sprom driver
+
+This driver needs an nvram driver and fetches the sprom values from the
+sprom and provides it to any other driver. The calibration data for the
+wifi chip the mac address and some more board description data is
+stores in the sprom.
