lib: sbi: Respect scounteren when emulating the time CSR
This optimization creates a correctness issue, as it prevents supervisor
software from restricting VS-mode or U-mode access to the time CSR for
its own purposes.
Closes: https://github.com/riscv-software-src/opensbi/issues/370
Fixes: ebc8ebc0f846 ("lib: sbi: Improve HPM CSR read/write emulation")
