mfd/power: ab8500: Push algorithm to power supply code
The charging algorithm header is only used locally in the power supply subsystem so push this down into drivers/power/supply and rename from the confusing "ux500_chargalg.h" to "ab8500-chargalg.h" for clarity: it is only used with the AB8500. This is another remnant of non-DT code needing to pass data from boardfiles, which we don't do anymore.
