Add generic cpu_idle support sparc32: - replace call to cpu_idle() with cpu_startup_entry() - add arch_cpu_idle() sparc64: - smp_callin() now include cpu_startup_entry() call so we can skip calling cpu_idle from assembler - add arch_cpu_idle() and arch_cpu_idle_dead() Signed-off-by:

The Kconfig symbol ARCH_HAS_DEFAULT_IDLE is unused. Commit a0bfa137 ("cpuidle: stop depending on pm_idle") removed the only place were it was actually used. But it did not remove its Kconfig entries (for sh and x86). Remove those two entries now. Signed-off-by:
