jah 233a78dc86 Use pmap_quick* functions in armv6 busdma, for bounce buffers and cache maintenance. This makes it safe to sync buffers that have no VA mapping associated with the busdma map, but may have other mappings, possibly on different CPUs. This also makes it safe to sync unmapped bounce buffers in non-sleepable thread contexts. 
Similar to r286787 for x86, this treats userspace buffers the same as unmapped buffers and no longer borrows the UVA for sync operations.
