[PATCH] SH: Delete unnecessary mov in the top of interrupt

[PATCH] SH: Delete unnecessary mov in the top of interrupt

[shinkoi2005]

Hi, all.

I think that to move INTEVT address to the scratch reg in the top of
interrupt is already unnecessary.
So this patch delete it.

That is indeed the case, good catch!

Applied, thanks.
