From: Zhang Rui <rui.zhang@xxxxxxxxx>
Mark ACPI sleep procfs interface as deprecated.
Remove two Kconfig options CONFIG_ACPI_SLEEP_PROC_SLEEP and CONFIG_ACPI_SLEEP_PROC_FS, as all the
ACPI sleep procfs interface is controlled by CONFIG_ACPI_PROCFS.
/proc/acpi/sleep is deprecated by /sys/power/state
/proc/acpi/alarm is deprecated by /sys/power/alarm
/proc/acpi/wakeup is deprecated by /sys/devices/acpi_system/.../device/sleep_state && wakeup
