M-profile CPUs only implement the ID registers as guest-visible if the CPU implements the Main Extension (all our current CPUs except the Cortex-M0 do). Currently we handle this by having the Cortex-M0 leave the ID register values in the ARMCPU struct as zero, but this conflicts with our design decision to make QEMU behaviour be keyed off ID register fields wherever possible. Explicitly code the ID registers in the NVIC to return 0 if the Main Extension is not implemented, so we can make the M0 model set the ARMCPU struct fields to obtain the correct behaviour without those values becoming guest-visible.
