hw/arm/bcm2835: Drop futile attempts at QOM-adopting memory 

The "bcm2835-peripherals" device's .instance_init() method
bcm2835_peripherals_init() attempts to make two memory regions QOM
children of the device.  This is futile, because memory_region_init()
already did.  The errors are ignored (a later commit will change
that).  Drop the useless calls.
