cpuidle: Init cpuidle only for present CPUs

for_each_possible_cpu() is currently used to initialize cpuidle
in below cpuidle drivers:
  drivers/cpuidle/cpuidle-arm.c
  drivers/cpuidle/cpuidle-big_little.c
  drivers/cpuidle/cpuidle-psci.c
  drivers/cpuidle/cpuidle-qcom-spm.c
  drivers/cpuidle/cpuidle-riscv-sbi.c

However, in cpu_dev_register_generic(), for_each_present_cpu()
is used to register CPU devices which means the CPU devices are
only registered for present CPUs and not all possible CPUs.

With nosmp or maxcpus=0, only the boot CPU is present, lead
to the failure:

  |  Failed to register cpuidle device for cpu1

Then rollback to cancel all CPUs' cpuidle registration.

Change for_each_possible_cpu() to for_each_present_cpu() in the
above cpuidle drivers to ensure it only registers cpuidle devices
for CPUs that are actually present.
