-Change the remaining GLIU1 port 5 register names from VIP (Video Input Port)

       to FG (FooGlue). As the GX2 has no VIP port.
-Change the Memmory setup MSR register names so they correspond better to the
       databook. (Part1)
       This is less confusing for beginners.
-Add a MSR printing function to northbridge.c like in the Geode LX code.
-Remove the AES register names.(GX2 has no AES registers)
-Delete some unused code.
-Clean up GX2 northbridge code  to match Geode LX code.
-Add missing copyright header to northbridge.c.
-Move hardcoded IRQ defining from northbridge.c to irq_tables.c .
