Subject: [PATCH 5/6] reset: rockchip: secure reset must be used by SCMI
While working on the rk3588 crypto driver, I loose lot of time
understanding why resetting the IP failed.
This is due to RK3588_SECURECRU_RESET_OFFSET being in the secure world,
so impossible to operate on it from the kernel.
All resets in this block must be handled via SCMI call.
