hwmon: End of I/O region off-by-one

Fix an off-by-one error in the I/O region declaration of two
hardware monitoring drivers (lm78 and w83781d.) We were requesting
one extra port at the end of the region.

This is a regression in 2.6.22 and could prevent other drivers from
loading properly.

Already applied to Linus' tree for 2.6.23:
