radeon/r200/r300/r600: make bo mapping be explicit

This moves the bo mapping outside the DMA layer and makes it explicit,
this should in theory make it simpler to split the clean up the dma/cmdbuf
linkage that I created before that is broken.

Tested on: r600, rv380 (tcl/no-tcl), rv200 (tcl/no-tcl)
