hw/s390x/ipl: enable LOADPARM in IPIB for a boot device
Insert the LOADPARM value to the IPL Information Parameter Block.
An IPL Information Parameter Block is created when "bootindex" is
specified for a device. If a user specifies "loadparm=", then we
store the loadparm value in the created IPIB for that boot device.
Initial patch from Eugene (jno) Dvurechenski.
