Heiko Schocher 780f13a9e1 hwmon: do not init sensors on startup
The U-Boot Design Principles[1] clearly say:

  Initialize devices only when they are needed within U-Boot, i.e. don't
  initialize the Ethernet interface(s) unless U-Boot performs a download
  over Ethernet; don't initialize any IDE or USB devices unless U-Boot
  actually tries to load files from these, etc. (and don't forget to
  shut down these devices after using them - otherwise nasty things may
  happen when you try to boot your OS).

So, do not initialize and read the sensors on startup.

Dirk Eibach 31c1bdd93d hwmon: Extend lm63.c to support LM64
This patch adds support for the National LM64 temperature
sensor with integrated fan control to lm63.c.
Main difference between LM63 and LM64 is 16°C offset in sensor
readings.
