Routine Description:
Initialize the AST EBI II environment. Only called if an AST machine
with EBI II capability. Gets table of EBI II call addresses in ebi_call_table.
Sets up EBI2_MMIOTable (EBI II Memory Mapped I/O Table).
Arguments:
none.
Return Value:
True if EBI II successfully initialized. False otherwise.
