Kyösti Mälkki f28dbe0c5d Only BSP CPU writes CMOS in bootblock code

CMOS accesses are not safe for multi-processor and only the BSP CPU
should count reboots and test CMOS sanity.

A questionable single byte CMOS read access from AP CPUs remains.
AP CPUs should always select the same romstage prefix as BSP CPU.
