sh: traps: Make is_dsp_inst() static

If CONFIG_SH_DSP=y (e.g. se7343_defconfig):

    arch/sh/kernel/traps_32.c:572:5: warning: no previous prototype for ‘is_dsp_inst’ [-Wmissing-prototypes]

There are no users outside this file, so make it static.

While at it, convert the dummy for the CONFIG_SH_DSP=n case from a macro
to a static inline function, to increase type-safety.
