mipssim_dma.c: set _bounce_thresh so that bounce buffering works.
Suggested by jmcneill@, thanks!

evbmips/mipssim: on mips64, probe for additional memory.

Probe for memory from above the ISA I/O hole and up to 16GB,
which acording to simonb@ is a somewhat arbitrary limit.

This makes it possible to specify e.g. "-m 2g" to qemu, and have
that memory be probed instead of being clamped to 508MB.
