[ARM] pxa: define zeus_power_off() only when CONFIG_PM enabled
Add some safety check for CONFIG_PM around zeus_power_off(). Without it linking can fail like this: arch/arm/mach-pxa/built-in.o: In function `zeus_power_off': e800.c:(.text+0x2bc8): undefined reference to `pxa27x_cpu_suspend' Signed-off-by: Stefan Schmidt <stefan@datenfreihafen.org> Acked-by: Marc Zyngier <maz@misterjones.org> Signed-off-by: Eric Miao <eric.y.miao@gmail.com>
