[PULL 10/13] lsi53c895a: disable reentrancy detection for script RAM |

From: Alexander Bulekov <alxndr@bu.edu>
As the code is designed to use the memory APIs to access the script ram,
disable reentrancy checks for the pseudo-RAM ram_io MemoryRegion.
In the future, ram_io may be converted from an IO to a proper RAM MemoryRegion.
