armv7m: Delete unused "ARM,bitband-memory" devices
These devices are optional, and enabled by property "enable-bitband".
armv7m_instance_init() creates them unconditionally, because the
property has not been set then. armv7m_realize() realizes them only
when the property is true. Works, although it leaves unrealized
devices hanging around in the QOM composition tree. Affects machines
microbit, mps2-an505, mps2-an521, musca-a, and musca-b1.
Delete the unused devices by making armv7m_realize() unparent them.
Visible in "info qom-tree"; here's the change for microbit:
/machine (microbit-machine)
/microbit.twi (microbit.i2c)
/microbit.twi[0] (qemu:memory-region)
/nrf51 (nrf51-soc)
/armv6m (armv7m)
/armv7m-container[0] (qemu:memory-region)
- /bitband[0] (ARM,bitband-memory)
- /bitband[0] (qemu:memory-region)
- /bitband[1] (ARM,bitband-memory)
- /bitband[0] (qemu:memory-region)
/cpu (cortex-m0-arm-cpu)
