This patch moves the data tables from driver/power/ab8500_bmdata.c to a common
header file include/linux/power/ab8500.h, so that other modules such as ab8500
hwmon can use these data. This patch also renames these variable names to
eliminate CamelCase warnings from checkpatch.pl, and adds const attribute to
these data.
