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. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> SVN-Revision: 40880

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.
