Board-pyramid: fix memory allocation bugs

*MEMTYPE_EBI1 was removed so replace that with MEMTYPE_EBI0 which is the same
*Manually allocate ADSP with MEMTYPE_EBI0 for the 624MB memory map since ADSP is in the SMI region in the 624MB memory map (when usually it's in the MEMTYPE_EBI0 region)
*Fix the address range for the MEMTYPE_EBI0 region (the highest address we can allocate to is 0x70000000, not 0x60000000)
