target/arm: Make Cortex-M3 and M4 default to 8 PMSA regions
The Cortex-M3 and M4 CPUs always have 8 PMSA MPU regions (this isn't a configurable option for the hardware). Make the default value of the pmsav7-dregion property be set per-cpu, so we don't need to have every user of these CPUs set it manually. (The existing default of 16 is correct for the other PMSAv7 core, the Cortex-R5.) This fixes a bug where we were creating the M3 and M4 with too many regions; most guest software would not notice or care, though, since it would just not use the registers associated with the unexpected extra regions.
