[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.
