LM85

[Margit Schubert-While]

Hi,
	I took a shot at the LM85 found on eg. Intel D845PE MB among
	others.
	At the moment, this is read-only, providing values for voltages,
	temps, fans, status in /proc/...

	There are "ifdefs" for the I2C ID and SYSCTL's, so doesn't rely
	on changes in the normal include files.
	"inttemp" is the LM85 temp.
	"proctemp" is the processor temp.
	"remtemp" is the temp at the edge of the keep-out zone.
	The rest are obvious.

	The 2V5 reading, at first glance, looks weird, however it is correct.
	The 845PESV has 1V5 here, although the scale muliplier is still 250.

	Register definitions are complete based on the Nat Sem specs at :
