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.
