s390/percpu: Provide arch_this_cpu_write() implementation
Provide an s390 specific implementation of arch_this_cpu_write()
instead of the generic variant. The generic variant uses a quite
expensive raw_local_irq_save() / raw_local_irq_restore() pair.
Get rid of this by providing an own variant which makes use of the new
percpu code section infrastructure.
With this the text size of the kernel image is reduced by ~1k (defconfig).
