ECKD DASDs have different IPL structures for CDL and LDL
formats. The current Ipl1 and Ipl2 structs follow the CDL
format, so we prepend "EckdCdl" to them. A new struct,
EckdLdlIpl1 is introduced and contains boot info for LDL.
So does this add support for LDL DASD, or does it simply enhance the
code? It's unclear from the desription alone.

Enhances. I'll reword it. Perhaps something along the lines of "Boot info
for LDL has been *moved* to a new struct, EckdLdlIpl1"

Also introduce structs for IPL stages 1 and 1b and for
disk geometry.
