sh: ptrace single stepping cleanups.
This converts the single stepping done by sh/sh64 ptrace implementations to use the generic user_enable/disable_single_step(), and subsequently rips out a lot of ptrace request cases that are now handled generically. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
