s390/ipl: add eckd support
This adds support to IPL from ECKD DASDs to linux. It introduces a few sysfs files in /sys/firmware/reipl/eckd: bootprog: the boot program selector clear: whether to issue a diag308 LOAD_NORMAL or LOAD_CLEAR device: the device to ipl from br_chr: Cylinder/Head/Record number to read the bootrecord from. Might be '0' or 'auto' if it should be read from the volume label. scpdata: data to be passed to the ipl'd program. The new ipl type is called 'eckd'.
