riscv: Remove SBI logger
...
SBI needs a physical address; it used to work before because of the buggy code by sheer chance.
Rather than trying to fix it the right way (find a mapping from virtual to physical both before
and after RMM) let's just throw it away. Serial logger works just fine for the early init logging.

A bunch of things are now printed a bit more compactly or without
interleaving of logs on a single line. Also a bunch of not that useful
logs are no longer printed by default at all.
