[PATCH] I2C: Move hwmon drivers (2/3)

Part 2: Move the driver files themselves.

Note that the patch "adds trailing whitespace", because it does move the
files as-is, and some files happen to have trailing whitespace.

- * The ADM1025 is a sensor chip made by Analog Devices. It reports up to 6
- * voltages (including its own power source) and up to two temperatures
- * (its own plus up to one external one). Voltages are scaled internally
- * (which is not the common way) with ratios such that the nominal value
- * of each voltage correspond to a register value of 192 (which means a
- * resolution of about 0.5% of the nominal value). Temperature values are
- * reported with a 1 deg resolution and a 3 deg accuracy. Complete
- * datasheet can be obtained from Analog's website at:
- *   http://www.analog.com/Analog_Root/productPage/productHome/0,2121,ADM1025,00.html
- *
- * This driver also supports the ADM1025A, which differs from the ADM1025
- * only in that it has "open-drain VID inputs while the ADM1025 has
- * on-chip 100k pull-ups on the VID inputs". It doesn't make any
- * difference for us.
- *
- * This driver also supports the NE1619, a sensor chip made by Philips.
- * That chip is similar to the ADM1025A, with a few differences. The only
- * difference that matters to us is that the NE1619 has only two possible
- * addresses while the ADM1025A has a third one. Complete datasheet can be
- * obtained from Philips's website at:
- *   http://www.semiconductors.philips.com/pip/NE1619DS.html
- *
- * Since the ADM1025 was the first chipset supported by this driver, most
- * comments will refer to this chipset, but are actually general and
- * concern all supported chipsets, unless mentioned otherwise.
