Subject: [PATCH] Include machine/_bus.h so that bus_space_[tag|handle]_t will
 be available.

It appears that all platforms except aarch64 are getting the file via
various header pollution, and ensuring _bus.h is included before any
openfirmware headers in every consumer of ofw/fdt stuff seems like more of
a career path than a task, so I'm taking this easy way out.
