[PATCH v2] target/riscv: Remove experimental prefix from "B" extension

[PATCH v2] target/riscv: Remove experimental prefix from "B" extension

[Rob Bradford]

This extension has now been ratified:
https://jira.riscv.org/browse/RVS-2006 so the "x-" prefix can be
removed.

Since this is now a ratified extension add it to the list of extensions
included in the "max" CPU variant.
