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.

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

Poll the ds1621 NV Memory Busy bit instead of waiting a static amount of
time for register writes.
Also add config retister bit defines.

CFG_EEPROM_PAGE_WRITE_BITS in various temperature
sensor drivers are not necessary
