Right now the regulator helpers expect raw register values for the range selectors. This is different from the voltage selectors, which are normalized as bitfield values. This leads to a bit of confusion. Also, raw values are harder to copy from datasheets or match up with them, as datasheets will typically have bitfield values. Make the helpers expect bitfield values, and convert existing users. The field in regulator_desc is renamed to |linear_range_selectors_bitfield|. This is intended to cause drivers added in the same merge window and out-of-tree drivers using the incorrect variable and values to break, preventing incorrect values being used on actual hardware and potentially producing magic smoke. Also include bitops.h explicitly for ffs(), and reorder the header include statements. While at it, also replace module.h with export.h, since the only use is EXPORT_SYMBOL_GPL.
