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'.
