1. convert *all* drivers that defines a config array to be defined by
    their own macro in hwmon.h, and then switch that macro to make the
    definitions be a u64 array at the same time as switching struct
     hwmon_channel_info.config

2. convert *all* drivers to use HWMON_CHANNEL_INFO() unconditionally,
    and switch that along with struct hwmon_channel_info.config.

3. add a new member to struct hwmon_channel_info such as
    "const u64 *config64" and then gradually convert drivers to use it.
    Once everyone is converted over, then remove "const u32 *config",
    optionally rename "config64" back to "config" and then re-patch all
    drivers. That'll be joyful, with multiple patches to drivers that
    need to be merged in sync with hwmon changes - and last over several
    kernel release cycles.

Alternatively, add another sensor type for the overflowing field, such as
hwmon_power_2 (or whatever), and use it for the additional attributes.

This is not going to be an easy change!

Neither is it necessary at this time.
