iio: adc: ab8500-gpadc: Fix off by 10 to 3

Browse Source 
commit 4f5434086d9223f20b3128a7dc78b35271e76655 upstream.

Fix an off by three orders of magnitude error in the AB8500
GPADC driver. Luckily it showed up quite quickly when trying
to make use of it. The processed reads were returning
microvolts, microamperes and microcelsius instead of millivolts,
milliamperes and millicelsius as advertised.
