RISC-V: cpuidle: fix Kconfig select for RISCV_SBI_CPUIDLE

There can be lots of build errors when building cpuidle-riscv-sbi.o.
They are all caused by a kconfig problem with this warning:

WARNING: unmet direct dependencies detected for RISCV_SBI_CPUIDLE
  Depends on [n]: CPU_IDLE [=y] && RISCV [=y] && RISCV_SBI [=n]
  Selected by [y]:
  - SOC_VIRT [=y] && CPU_IDLE [=y]

so make the 'select' of RISCV_SBI_CPUIDLE also depend on RISCV_SBI.
