board/km/common: fix pnvramaddr and varaddr

Take into account SDRAM_BASE address when calculating pnvramaddr and
varaddr offsets.
Up to now Keymile designs had SDRAM_BASE equal to zero and the offsets
where calculated correctly, this fix is for the upcoming designs that
have SDRAM_BASE different then zero.
