R_RISCV_CALL/R_RISCV_CALL_PLT distinction is not necessary and R_RISCV_CALL has been deprecated. Since https://reviews.llvm.org/D132530 `call foo` assembles to R_RISCV_CALL_PLT. The `@plt` suffix is not useful and can be removed now (matching AArch64 and PowerPC). GNU assembler assembles `call foo` to RISCV_CALL_PLT since 2022-09 (70f35d72ef04cd23771875c1661c9975044a749c). Without this patch, unconditionally changing MO_CALL to MO_PLT could create `jump .L1@plt, a0`, which is invalid in LLVM integrated assembler and GNU assembler.
