devicetree.h: Covert DT_{REG,IRQ}_HAS_IDX macros to IS_ENABLED form

Browse source 
With the generation of DT_N_<node-id>_{REG,IRQ}_IDX_<idx>_EXISTS
defines, we can now use the IS_ENABLED macro to implement DT_REG_HAS_IDX
and DT_IRQ_HAS_IDX.  This matches how other DT_*_HAS_* macros are
implemented as well as lets us utilize these macros with COND_CODE_1.
