[netdrvr] Convert madgemc to new MCA API.

Browse Source 
Now that all tms380 devices have a valid
struct device with dma_mask, remove dmalimit from tmsdev_init().

Kconfig: depend tms380tr and madgemc on MCA.
abyss.c, proteon.c, skisa.c, tmspci.c, tms380tr.h:
  remove dmalimit parameter from tmsdev_init().
tms380tr.c: use device->dma_mask instead of dmalimit.
madgemc.c: move to new MCA API using struct device.
