The LM63 and compatible devices have a lookup table to control the fan
speed automatically. Expose it in sysfs. Values are cached for 5
seconds, independently of the other register values to avoid slowing
down "sensors". We might make the table values writable in the future.

On the LM64, the tachometer function has a dedicated pin and fan speed
monitoring is always enabled.

On LM96163, the external temperature sensor type is configurable to
either a thermal diode or a 3904 transistor. The chip reports a wrong
temperature if misconfigured. Add writable attribute to support it.

LM96163 is an enhanced version of LM63 with improved PWM resolution. Add chip
detection code as well as support for improved PWM resolution if the chip is
configured to use it.

The LM64 appears to be an LM63 with added GPIO lines. Add support for the
hwmon functionality - GPIO can be added at some later stage if someone
has a need for them.

Part 3: Move the drivers documentation, plus two general documentation
files.
Note that the patch "adds trailing whitespace", because it does move the
files as-is, and some files happen to have trailing whitespace.
