sparc32: always register a PROM based early console

Browse source 
Do not require user to add "-p" to boot arguments to see
early info printed to prom console.

This is similar to the sparc64 functionality - which was added with:
3c62a2d347 ("[SPARC64]: Always register
a PROM based early console.")
