On most PowerPC Macs, the PMU driver uses the shift register and
IO port B from a single VIA chip.
On 68k and early PowerPC PowerBooks, the driver uses the shift register
from one VIA chip together with IO port B from another.
Replace via with via1 and via2 to accommodate this. For the
CONFIG_PPC_PMAC case, set via1 = via2 so there is no change.
