sim: mips: rework dynamic printf logic to avoid compiler warnings
The compiler doesn't like passing non-constant strings to printf
functions, so tweak the code to always pass one in. This code is
a little more verbose, but it's probably the same performance.
The macro usage is a bit ugly, but maybe less than copying &
pasting the extended conditional format logic.
