ab8500_btemp: Get rid of 'enum adc_therm'

This is the same as abx500_adc_therm, but when the former is used,
the following warning flood pops up:

drivers/power/ab8500_btemp.c: In function 'ab8500_btemp_batctrl_volt_to_res':

ab8500_btemp.c:551:25: warning: comparison between 'enum abx500_adc_therm' and 'enum adc_therm' [-Wenum-compare]

This patch fixes the issue by switching the driver to use more
namespace-friendly enum.
