Internal: introduce processor enables and abort if top/bottom alignment is unknown
The internal programmer needs correct information about flash_base and
chip window top/bottom alignment on non-x86 before it can be used. Abort
any internal programmer action for now until the code is fixed.
Add the concept of a processor enable for systems where flashing is
impacted by processor settings or processor model.
Corresponding to flashrom svn r1031.
