busdma - Fix bouncebuffer operation for 64 bit builds / mountroot & boot issues
* BUF_SPACE_MAXADDR was incorrectly defined for 64 bit builds, effectively
disabling bounce buffers. Fixed.
* This created issues with drivers (particularly NATA) which only support
32 bit physical addresses, causing x86_64 machines to fail to boot or
to blow up.
