[IA64] Only build arch/ia64/kernel/acpi.o when CONFIG_ACPI
The following commit broke the ia64 sim_defconfig build:
3b2b84c0b81108a9a869a88bf2beeb5a95d81dd1
ACPI: processor: driver doesn't need to evaluate _PDC
This is because it added:
+#include <acpi/processor.h>
To arch/ia64/kernel/acpi.c. Unfortunately, the ia64_simdefconfig does
not turn on CONFIG_ACPI, and we get build errors.
The fix described in $subject seems to be the most sensible way to
untangle the mess.
The other issue is that acpi_get_sysname() is required for all configs,
most of which define CONFIG_ACPI, but are not CONFIG_IA64_GENERIC. Turn
it into an inline to cover the "non generic" ia64 configs; to prevent
a duplicate definition build error, we need to wrap the definition in
acpi.o inside an #ifdef.
Finally, move the pm_idle and pm_power_off exports into process.c (which
is always built), similar to other architectures, and allow the sim
defconfig to link.
