[PATCH v2 3/9] target/riscv: add shcounterenw


From: Daniel Henrique Barboza
Subject: [PATCH v2 3/9] target/riscv: add shcounterenw
Date: Wed, 18 Dec 2024 08:40:20 -0300

shcounterenw is defined in RVA22 as:

"For any hpmcounter that is not read-only zero, the corresponding bit in
hcounteren must be writable."

This is always true in TCG so let's claim support for it.
