Kito Cheng via Newlib d572c4482b RISC-V: Support Zfinx/Zdinx extension.
Zfinx/Zdinx are new extensions ratified in 2022, it similar to F/D extensions,
support hard float operation for single/double precision, but the difference
between Zfinx/Zdinx and F/D is Zfinx/Zdinx is operating under general purpose
registers rather than dedicated floating-point registers.

This patch improve the hard float support detection for RISC-V port, so
that Zfinx/Zdinx can have better/right performance.
