c65b8f128e soc/intel/apollolake: pre-evaluate gpio number values
To allow sharing macros in ASL as well as C the macros can't
have complex expression because the ASL compiler does not
evaluate those expressions. To that end, just pre-calculate
the values. Lastly, add N_OFFSET and utilize it for symmetry.
