[PATCH] x86_64/acpi: make kernel to be compiled when  CONFIG_ACPI_NUMA is set and power management with acpi is not enabled

when CONFIG_ACPI_NUMA is set, and power management with acpi is not used. the kernel can not be compiled.

drivers/acpi/bus.c: In function ‘acpi_bus_get_power’:
drivers/acpi/bus.c:160: warning: implicit declaration of function ‘acpi_power_get_inferred_state’
drivers/acpi/bus.c: In function ‘acpi_bus_set_power’:
drivers/acpi/bus.c:230: warning: implicit declaration of function ‘acpi_power_transition’
...

drivers/built-in.o: In function `acpi_bus_get_power':
: undefined reference to `acpi_power_get_inferred_state'
drivers/built-in.o: In function `acpi_bus_set_power':
: undefined reference to `acpi_power_transition'
drivers/built-in.o: In function `acpi_bus_set_power':
: undefined reference to `acpi_power_transition'
drivers/built-in.o: In function `acpi_bus_generate_event':

so use CONFIG_ACPI_POWER and CONFIG_ACPI_SYTEM to comment function about set/get power and event.
