cpu/amd/fam10h-15h: Set PowerStepUp/PowerStepDown on Fam15h

Multilink Family 15h processors were being configured with an
    incorrect PowerStepUp/PowerStepDown value.  Set the value
    according to the BKDG, and clean up the terrible formatting
    of the power_up_down() function that led to the incorrect
    values being overlooked until now.

Also change u32 declarations to uint32_t in modified functions.
