riscv: alternatives: Drop the underscores from the assembly macro names

The underscores aren't needed because there isn't anything already
named without them and the _CFG extension. This is a bit of a cleanup
by itself, but the real motivation is for a coming patch which would
otherwise need to add two more underscores to these macro names,
i.e. ____ALTERNATIVE_CFG, and that'd be gross.
