Remove text stating C.ADDI4SPN is RV32C/RV64C-only (#223)

The paragraph of text describing C.ADDI4SPN states the instruction is
RV32C/RV64C-only, but the opcode map indicates the instruction is
available for RV128C too.  This change updates the descriptive text,
assuming that the opcode map is correct.
