timestamp: add generic cache region

In order to accommodate tracking timestamps in all the
    __PRE_RAM__ stages (bootblock, verstage, romstage, etc)
    of a platform one needs to provide a way to specify
    a persistent region of SRAM or cache-as-ram to store
    the timestamps until cbmem comes online. Provide that
    infrastructure.
