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.

Hi guys,
As recently discussed (thanks Paul!), we will try yet another (3rd) path for our
NVRAM driver, this time it will be drivers/firmware/.
However this will require some time as I want to give ppl chance to review it
and probably we will need to discuss it too.
So meanwhile I'd like to move just a header file to the include/linux/. I
believe it won't raise any/too many objections and it should strip down
further discussions about bcm47xx_nvram.c.
