RISC-V/testsuite: constraint some of tests to hard_float

Commit 9ddd44b58649d1d ("RISC-V: Provide `fmin'/`fmax' RTL pattern") added
tests which check for hard float instructions which obviously fails on
soft-float ABI builds.

And my recent commit b646d7d279ae ("RISC-V: Inhibit FP <--> int register
moves via tune param") is guilty of same crime.

So constraint with "dg-require-effective-target hard_float"

This reduces bunch of new RV failures.
