Subject: [PATCH] RISC-V: Fix T-Head Fmv vendor extension encoding
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A recent change in the XTheadFmv spec fixed an encoding bug in the
document. This patch changes the code to follow this bugfix.

Spec patch can be found here:
