kernel: banner: cleanup #ifdef's

Browse source 
Cleanup the mess of duplicate function definitions, unnecessary
variables and duplicate strings. All banner strings are now constant in
ROM. Also fixes a double space between the end of the version string and
the trailing `***` when there is no boot delay.
