Use device->state_count instead of driver->state_count in
cpuidle_play_dead(), ladder_select_state() and menu_select().
This allows cpuidle drivers to override maximum allowable
state number for a given device, which is what some cpuidle
drivers would like to do (i.e. EXYNOS cpuidle driver).

Currently PM domains support will be enabled for EXYNOS4x12 SoCs
only if EXYNOS4210 SoC or EXYNOS5250 SoC support is also enabled.
Fix it by explicitly selecting PM domains support (if PM support
is enabled) by SOC_EXYNOS4212 and SOC_EXYNOS4412 config options.
