sh: Rip out special unknown machvec.
This kills off the BareCPU board as a "special" machvec, rather, we leave this as a default for when no other vector is available, or when we want to use it in combination with other vectors for testing with generic ops. As sh_mv is copied out anyways (or overloaded when an alternate vector is explicitly selected), this doesn't consume any additional memory. The generic machvec can be forcibly selected with sh_mv=generic, or by not having any other boards enabled. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

- bool "BareCPU"
- help
- "Bare CPU" aka "unknown" means an SH-based system which is not one
- of the specific ones mentioned above, which means you need to enter
- all sorts of stuff like CONFIG_MEMORY_START because the config
- system doesn't already know what it is. You get a machine vector
- without any platform-specific code in it, so things like the RTC may
- not work.

- This option is for the early stages of porting to a new machine.
