ARM: 6997/1: ep93xx: increase NR_BANKS to 16 for support of 128MB RAM

Browse Source 
I've got hands on one ts-7300 board, which is equiped with 128MB RAM in two
64MB memory chips, so it's 16 banks/8MB each. Without this patch, the bootmem
init code complains about small NR_BANKS number and only lower 64MB is
accessible.
