hw/arm/mps2-tz: Fix MPC setting for AN524 SRAM block
The AN524 has three MPCs: one for the BRAM, one for the QSPI flash,
and one for the DDR. We incorrectly set the .mpc field in the
RAMInfo struct for the SRAM block to 1, giving it the same MPC we are
using for the QSPI. The effect of this was that the QSPI didn't get
mapped into the system address space at all, via an MPC or otherwise,
and guest programs which tried to read from the QSPI would get a bus
error. Correct the SRAM RAMInfo to indicate that it does not have an
associated MPC.
