hwmon: put HWMON_CHANNEL_INFO() initializers in rodata 



HWMON_CHANNEL_INFO() is supposed to be used as initializer for arrays of
const struct hwmon_channel_info *. However, without explicit const,
HWMON_CHANNEL_INFO() creates mutable compound literals, and the const
pointers point at the mutable data. Add const to place the data in
rodata.
