The nvram_get function was never in the mainline kernel, it only
existed in an external OpenWrt patch. Use nvram_getenv function, which
is in mainline and use an include instead of an extra function
declaration.
et0macaddr contains the mac address in text from like
00:11:22:33:44:55. We have to parse it before adding it into macaddr.

nvram_parse_macaddr will be merged into asm/mach-bcm47xx/nvram.h though
the MIPS git tree and will be available soon. It will not build now
without nvram_parse_macaddr, but it haven't done before.
