INA220 is register compatible to INA219, and INA230 is register compatible to
INA226, so all we need to do is to add name aliases for those two chips.

Replace per-device initialization and per-device calculation code with
per-device configuration data, which is then used to configure the chip and
perform calculations based on that data.

This patch reduces code size by more than 400 bytes on x86_64.

MAX1110 is similar to MAX1111, with 8 instead of 4 channels. MAX1112 and MAX1113
are similar to MAX1110 and MAX1111, with 4.096V reference voltage instead of
2.048V.

Declare an array of platform_device_id, instead of registering a driver
for each supported chip. This makes the code cleaner.
Also add a module description.

The MAX197 is an A/D converter, made by Maxim. This driver currently
supports the MAX197, and MAX199. They are both 8-Channel, Multi-Range,
5V, 12-Bit DAS with 8+4 Bus Interface and Fault Protection.

The available ranges for the MAX197 are {0,-5V} to 5V, and {0,-10V} to
10V, while they are {0,-2V} to 2V, and {0,-4V} to 4V on the MAX199.

This patch brings basic support for the Analog Devices ADT7410 temperature
sensor. The following functionality has been implemented:

  * get current temperature
  * get/set minimum, maximum and critical temperature
  * get/set hysteresis
  * get alarm events for minimum, maximum and critical temperature

All implemented sysfs attributes have been sucessfully tested at temperatures
of 15°C to 40°C.
