bcm2835_mbox/property: replace ldl_phys/stl_phys with endian-specific accesses

PMM pointed out that ldl_phys and stl_phys are dependent on the CPU's
endianness, whereas device model code should be independent of
it. This changes the relevant Raspberry Pi devices to explicitly call
the little-endian variants.
