mac68k: rework SWIM platform device
Adjust the platform device code to conform with the code style used in the rest of this patch series. No need to name resources nor to register devices which are not applicable. Signed-off-by: Finn Thain <fthain@telegraphics.com.au> Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
