s390/ctlreg: add local_ctl_load() and local_ctl_store()

Add local_ctl_load() and local_ctl_store() which load and store contents
for only a single control register.

This allows for easier to read code, but also better type checking,
since __local_ctl_load() and __local_ctl_store() do not come with any
type checking at all (which will be changed with subsequent patches).
