[PATCH 2/2] arm/pxa: Let zeus.c link without CONFIG_PM enabled.

[Stefan Schmidt]

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'

This smells a bit fishy as zeus_power_off() is only mapped to pm_power_off and
that one seems to come and go to nowhere. Is this any magic I don't get on a
first glance?
