[PATCH] cpuidle: move ARCH_NEEDS_CPU_IDLE_COUPLED Kconfig option

[Arnd Bergmann]

There is no reason why ARCH_NEEDS_CPU_IDLE_COUPLED needs to be
hidden inside of "if CPU_IDLE", since it is a silent option.
Moving it outside lets platforms select this symbol unconditionally,
which avoid a warning from the ARM omap2plus_defconfig build:

warning: (ARCH_OMAP4 && ARCH_TEGRA_2x_SOC) selects
	ARCH_NEEDS_CPU_IDLE_COUPLED which has unmet direct
	dependencies (CPU_IDLE)
