powerpc: Use new CPU feature bit to select 2.06 tlbie
This removes MMU_FTR_TLBIE_206 as we can now use CPU_FTR_HVMODE_206. It also changes the logic to select which tlbie to use to be based on this new CPU feature bit. This also duplicates the ASM_FTR_IF/SET/CLR defines for CPU features (copied from MMU features).
