Added rules to the gf180mcu tech file for magic to close open
areas in NPLUS and PPLUS that are smaller than the required
minimum.  Updated references to get the updates to the SRAM
blocks for gf180mcu, which were violating those rules and
needed a simpler layout for NPLUS and PPLUS through the SRAM
core array area.
