[PATCH] tools: riscv: Fixed misalignment of CSR related definitions

[cp0613 at linux.alibaba.com]

From: Chen Pei <cp0613 at linux.alibaba.com>

The file tools/arch/riscv/include/asm/csr.h borrows from
arch/riscv/include/asm/csr.h, and subsequent modifications
related to CSR should maintain consistency.

Fixes: 16b0bde9a37c ("RISC-V: KVM: Add perf sampling support for guests")
Fixes: d1927f64e0e1 ("RISC-V: Fix the typo in Scountovf CSR name")
