Fix a long-standing "leprobe: cannot map memory-area" error during probe.
PAM and ROTHRON VME LANCE seem to have 64KB RAM, but the register
address region are overwrapped, so we cannot map both of them via
bus_space_map(9) that checks regions using extent(9).
To work around this, just use only 32KB RAM for buffers.
XXX: not sure if anyone tried these VME LANCE variants
