sh: Restrict DSP support to specific CPUs.
Not all CPUs support the DSP, and this leads to problems when mixing and matching CPU types and DSP opcodes. Fix this up by only allowing CONFIG_SH_DSP to be enabled for the CPUs that explicitly have such a block. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

Selecting this option will enable support for SH processors that
have DSP units (ie, SH2-DSP, SH3-DSP, and SH4AL-DSP).
