s390x: protvirt: SCLP interpretation
SCLP for a protected guest is done over the SIDAD, so we need to use
the s390_cpu_pv_mem_* functions to access the SIDAD instead of guest
memory when reading/writing SCBs.
To not confuse the sclp emulation, we set 0x4000 as the SCCB address,
since the function that injects the sclp external interrupt would
reject a zero sccb address.
