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.

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