Subject: hwmon: (amc6821) sign extension temperature

From: Jared Bents <jared.bents@rockwellcollins.com>

commit 4538bfbf2d9f1fc48c07ac0cc0ee58716fe7fe96 upstream.

Converts the unsigned temperature values from the i2c read
to be sign extended as defined in the datasheet so that
negative temperatures are properly read.
