Log Message:
bcm2835: make vchiq and vcaudio work on big-endian kernels.

VCHIQ shared memory structures and VC audio messages are little-endian.
Convert whole fields to/from little-endian at the shared-memory boundary
and in VC audio payloads so that big-endian kernels can use vchiq and
vcaudio properly.

Audio playback tested on Raspberry Pi 3B running NetBSD/earmv7hfeb and
NetBSD/aarch64eb.  No visible/audible regression on little-endian
NetBSD/earmv7hf and NetBSD/aarch64.
