Subject: [PATCH 01/17] MIPS: BCM47XX: move the nvram header file into common
 space

Moving mach-bcm47xx/bcm47xx_nvram.h to include/linux/bcm47xx_nvram.h
makes it possible to reuse this header on the ARM based bcm47xx/bcm53xx
SoCs (e.g. BCM5301X devices). Broadcom uses ARM CPUs in their new SoC
form the bcm47xx and bcm53xx line, but many other things like nvram
stayed the same.

This is a preparation for adding a new nvram driver, which can be used
by the ARM SoC and the MIPS SoC code. The device drivers accessing
nvram do not have to care about ARM or MIPS SoC version.
