mb/asus/p2b: Enable hardware monitor access via I/O on ISA bus
Set up a 8-byte I/O range at 0x290-0x297 as PIIX4's generic device 9,
which activates a chip select when this range is accessed.
On the P2B family it connects to the W83781D hardware monitor,
allowing access to it over the ISA bus, just like vendor firmware.
Apparently this does not work on p3b-f, but no ill effects observed
either.
TEST=On p2b-ls lm-sensors can detect chip and get readings over ISA.
