link Agesa into bootblock

For AGESA targets the APs are started by the BSP in romstage and need
to jump past the bootblock into the romstage. When there is a separate
romstage this is complicated as the APs in boot need to know where
to jump in romstage. This is done by setting a pointer in BIOSRAM.

When the romstage is linked inside the bootblock there is no need for
such tricks as the symbol for the AP jump address can directly be
referenced.
