hwmon: (lm90) Improve PEC support

Browse source

PEC (packet error checking) support for ADM1032 is currently only enabled
if the chip was auto-detected, but not if a chip is instantiated
explicitly. Always enable PEC support by introducing a chip feature flag
indicating partial PEC support. Also, for consistency, disable PEC support
by default to match existing functionality if the chip was not auto-
detected.

At the same time, introduce generic support for PEC with a separate feature
flag. This will be used when support for chips with full PEC functionality
is added.
