Subject: [PATCH v2 3/5] dt-bindings: riscv: d requires f

From: Conor Dooley <conor.dooley@...rochip.com>

Per the specifications, the d extension for double-precision floating
point operations depends on the f extension for single-precision floating
point. Add that requirement to the bindings. This differs from the
Linux implementation, where single-precious only is not supported.
