Use KS2_ prefix in all definitions, for that replace K2HK_ prefix and add KS2_ prefix where it's needed. It requires to change names also in places where they're used. Align lines and remove redundant definitions in kardware-k2hk.h at the same time. Using common KS2_ prefix helps resolve redundant redefinitions and adds opportunity to use KS2_ definition across a project not thinking about what SoC should be used. It's more convenient and we don't need to worry about the SoC type in common files, hardware.h will think about that. The hardware.h decides definitions of what SoC to use.
