Peter Maydell March 5, 2021, 5:15 p.m. UTC 
Add support for the mps3-an524 board; this is an SSE-200 based FPGA
image, like the existing mps2-an521.  It has a usefully larger amount
of RAM, and a PL031 RTC, as well as some more minor differences.

In real hardware this image runs on a newer generation of the FPGA
board, the MPS3 rather than the older MPS2.  Architecturally the two
boards are similar, so we implement the MPS3 boards in the mps2-tz.c
file as variations of the existing MPS2 boards.
