hw/arm/mps2-tz: Fix MPC setting for AN524 SRAM block

hw/arm/mps2-tz: Assert if more than one RAM is attached to an MPC

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.

2.20.1

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.

These sections need to be wrapped in a block-level element, such as

Paragraph in order for them to be rendered into Texinfo correctly.

Before (e.g.):

<section ids="qapidoc-713">

<title>If</title>

<literal>defined(CONFIG_REPLICATION)</literal>

</section>

became:
