ACPI / PM: Fix build problem related to acpi_target_system_state()
Commit b87b49cd0efd ("ACPI / PM: Move device PM functions related to sleep
states") declared acpi_target_system_state() for CONFIG_PM_SLEEP whereas
it is only defined for CONFIG_ACPI_SLEEP, resulting in the following link
error:
drivers/built-in.o: In function `acpi_pm_device_sleep_wake':
drivers/acpi/device_pm.c:342: undefined reference to `acpi_target_system_state'
drivers/built-in.o: In function `acpi_dev_suspend_late':
drivers/acpi/device_pm.c:501: undefined reference to `acpi_target_system_state'
drivers/built-in.o: In function `acpi_pm_device_sleep_state':
drivers/acpi/device_pm.c:221: undefined reference to `acpi_target_system_state'
Define it only for CONFIG_ACPI_SLEEP and fallback to a dummy definition
for other configs.
[rjw: The problem only occurs for exotic .configs in which
HIBERNATE_CALLBACKS is selected by XEN_SAVE_RESTORE and neither
SUSPEND nor HIBERNATION is set.]
