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.
