hwmon: (ina2xx) Mark regmap_config as const
Recent versions of checkpatch complain that struct regmap_config
should be declared as const.
WARNING: struct regmap_config should normally be const
Doing so reveals a potential problem in the driver: If both supported
chips are present in a single system, the maximum number of registers
may race when devices are instantiated since max_registers is updated
in the probe function. Solve the problem by setting .max_registers to the
maximum register address of all supported chips. This does not make a
practical difference while fixing the potential race condition and reducing
code complexity.
