hw/arm/bcm2835_peripherals: Name various address spaces

Various address spaces from the BCM2835 are reported as
'anonymous' in memory tree:

  (qemu) info mtree

  address-space: anonymous

Since the address_space_init() function takes a 'name' argument,
set it to correctly describe each address space:

  (qemu) info mtree
