The SRAM at 0x2000_0000 is part of the SSE-200 itself, and we model
it that way in hw/arm/armsse.c (along with the associated MPCs).  We
incorrectly also added an entry to the RAMInfo array for the AN524 in
hw/arm/mps2-tz.c, which was pointless because the CPU would never see
it.  Delete it.

The bug had no guest-visible effect because devices in the SSE-200
take priority over those in the board model (armsse.c maps
s->board_memory at priority -2).
