powerpc: permanently include 8xx registers in reg.h
Most 8xx registers have specific names, so just include reg_8xx.h all the time in reg.h in order to have them defined even when CONFIG_PPC_8xx is not selected. This will avoid the need for #ifdefs in C code. Guard SPRN_ICTRL in an #ifdef CONFIG_PPC_8xx as this register has same name but different meaning and different spr number as another register in the mpc7450.
