I've committed the patch below to fix a build failure after
rsqrt_optab changes applied.  Now rsqrtsf2 is expected to have
just 2 operands and HAVE_rsqrtsf2 should be simple enough.
Tested with build for sh4-unknown-linux-gnu and running
gcc.target/sh/sh4a-fsrra.c.

Regards,
	kaz

	* config/sh/sh.md (rsqrtsf2): Adjust for canonical form with unspec.
