Introduce Secure-IPL (SIPL) facility.
Use the abbreviation CBL (Consolidated-Boot-Loader facility at bit 0 of
byte 136) to represent bytes 136 and 137 for IPL device facilities of the
SCLP Read Info block.
Availability of SIPL facility is determined by byte 136 bit 1 of the
SCLP Read Info block.
When SIPL facility is installed, the IPL Parameter Block length must
contains value that is multiple of 8 bytes.
