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.

7d85f1dc5c ds1621: Fix negative temperature readings
Fix bug where signed data was processed as unsigned.  The bug previously
resulted in negative temperature readings wrapping around, eg -10 became
245.

c3e5fa0b53 ds1621: Poll for register write completion
Poll the ds1621 NV Memory Busy bit instead of waiting a static amount of
time for register writes.

Also add config retister bit defines.
