hw/misc/tz-msc: Model TrustZone Master Security Controller
Implement a model of the TrustZone Master Securtiy Controller,
as documented in the Arm CoreLink SIE-200 System IP for
Embedded TRM (DDI0571G):
https://developer.arm.com/products/architecture/m-profile/docs/ddi0571/g
The MSC is intended to sit in front of a device which can
be a bus master (eg a DMA controller) and programmably gate
its transactions. This allows a bus-mastering device to be
controlled by non-secure code but still restricted from
making accesses to addresses which are secure-only.
