bootblock: Provide some common prototypes The split of bootblock initialisation to cpu, northbridge and southbridge is not specific to intel at all, create new header <arch/bootblock.h> as AMD will want some of these too.

intel/i82801gx: Store initial timestamp Upgrade the ICH7 bootblock to store an initial timestamp like we do it since Sandy Brigde. I've checked the datasheets for the used scratchpad registers and grepped for their usage. I'm pretty sure that they aren't used on any ICH7 based board (for anything before the usual S3-resume indication).
