linux-core to free pci memory without freeing the structure. Linux-core
internals often create pci dma handle structures on the stack due to
the lack of a drm_local_map_t to store them in properly. Fix the
original drm_pci_free to actually free the dma handle structure instead
of leaking it.

with IOMMUs and such. There is one usage of the forbidden vtophys()
left in drm_scatter.c which will be fixed up soon. This required a KPI
change for drm_pci_alloc/free() to return/use a drm_dma_handle_t that
keeps track of os-specific bits, rather than just passing around the
vaddr/busaddr/size.
