CM3: Make ACTLR bit definitions conditional 

The ACTLR register itself is conditional on chip revision, but its
bit definitions were always defined.

Make the the bit definitions also conditional, so it is possible to
produce portable code that sets DISDEFWBUF if available:

    #ifdef SCnSCB_ACTLR_DISDEFWBUF_Msk
       SCnSCB->ACTLR |= SCnSCB_ACTLR_DISDEFWBUF_Msk;
    #endif

(cherry-picked from CMSIS b2b04dbeece0a046556bfc320bef6b20bef3f16f)
