MIPS: BCM47xx: Move NVRAM header to the include/linux/.

There are two reasons for having this header in the common place: 1) Simplifying drivers that read NVRAM entries. We will be able to safely call bcm47xx_nvram_* functions without #ifdef-s. 2) Getting NVRAM driver out of MIPS arch code. This is needed to support BCM5301X arch which also requires this NVRAM driver. Patch for that will follow once we get is reviewed.
