[PATCH linux-next (v2) 1/3] MIPS: bcm963xx: Add nvram structure

[Simon Arlott <simon-A6De1vDTPLDsq35pWSNszA@public.gmane.org>]

The BCM963xx has multiple nvram variants across different SoCs with
additional checksum fields added whenever the size of the nvram was
extended.

Signed-off-by: Simon Arlott <simon-A6De1vDTPLDsq35pWSNszA@public.gmane.org>

v2: Use external struct bcm963xx_nvram definition for bcm963268part.
