riscv: Enable ARCH_SUSPEND_POSSIBLE for s2idle
With this configuration opened, the basic platform-independent s2idle is
provided by the sole "s2idle" string in `/sys/power/mem_sleep`.
At the end of s2idle, harts will hit the `wfi` instruction or enter the
SUSPENDED state through the sbi_cpuidle driver. The interrupt of possible
wakeup devices will be kept to wake the system up.
And platform-specific sleep states can be provided by future ACPI and
SBI SUSP extension support.
