Peter Maydell 91c0a79891 hw/arm/mps2-tz: Assert if more than one RAM is attached to an MPC 
Each board in mps2-tz.c specifies a RAMInfo[] array providing
information about each RAM in the board.  The .mpc field of the
RAMInfo struct specifies which MPC, if any, the RAM is attached to.
We already assert if the array doesn't have any entry for an MPC, but
we don't diagnose the error of using the same MPC number twice (which
is quite easy to do by accident if copy-and-pasting structure
entries).

Enhance find_raminfo_for_mpc() so that it detects multiple entries
for the MPC as well as missing entries.

/* The MPS2 and MPS2+ dev boards are FPGA based (the 2+ has a bigger
* FPGA but is otherwise the same as the 2). Since the CPU itself
* and most of the devices are in the FPGA, the details of the board
* as seen by the guest depend significantly on the FPGA image.
* This source file covers the following FPGA images, for TrustZone cores:
* "mps2-an505" -- Cortex-M33 as documented in ARM Application Note AN505
* "mps2-an521" -- Dual Cortex-M33 as documented in Application Note AN521
* "mps2-an524" -- Dual Cortex-M33 as documented in Application Note AN524
* "mps2-an547" -- Single Cortex-M55 as documented in Application Note AN547
*

* Notes which document the FPGA images can be found here:

* (ARM ECM0601256) for the details of some of the device layout:
* https://developer.arm.com/documentation/ecm0601256/latest
* Similarly, the AN521 and AN524 use the SSE-200, and the SSE-200 TRM defines
* most of the device layout:
* https://developer.arm.com/documentation/101104/latest/
