hw/arm: Set ignore_memory_transaction_failures for most ARM boards
Set the MachineClass flag ignore_memory_transaction_failures
for almost all ARM boards. This means they retain the legacy
behaviour that accesses to unimplemented addresses will RAZ/WI
rather than aborting, when a subsequent commit adds support
for external aborts.
The exceptions are:
* virt -- we know that guests won't try to prod devices
that we don't describe in the device tree or ACPI tables
* mps2 -- this board was written to use unimplemented-device
for all the ranges with devices we don't yet handle
New boards should not set the flag, but instead be written
like the mps2.
