You have inconsistent mixes of tabs and spaces here and in several
other places.

Do you have in mind a scenario where the plain "renesas,sh"
fallback-compatible tag makes sense? Linux (or any kernel or baremetal
app) can't treat all sh as the same because the trap mechanism is
different for sh1/2 and sh3/4. Declaring that it's sh3-compatible
might make sense but I still doubt it has much practical usefulness.
