[PATCH] tms380tr: move to DMA API

This patch makes tms380tr use the new DMA API.  Now that on Alpha, this API
also supports bus master DMA for ISA (platform) devices, i changed the
driver to use this new API.

This also works around a bug in the firmware loader: The example provided
in Documentation/firmware_class no longer works, as the firmware loader now
calls get_kobj_path_length() and the kernel promptly oopses, as the
home-grown device doesn't have a parent.  Of course, this doesn't happen
with a "real" device which has its bus (or pseudo bus in the case of
platform) as parent.

Converted tms380tr to use new DMA API:
  - proteon.c, skisa.c: use platform pseudo bus to create a struct device
  - Space.c: delete init hooks
  - abyss.c, tmspci.c: pass struct device to tms380tr.c
  - tms380tr.c, tms380tr.h: new DMA API, use real device fo firmware loader
