s390-ccw: refactor boot map table code
s390-ccw:
for loadparm will override all boot menu options.
If loadparm=PROMPT, then the menu will be enabled without a
timeout.
The absence of any boot options on the command line will flag
to later use the zipl boot loader values.

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. Boot info for LDL
has been moved to a new struct: EckdLdlIpl1.

The s390-ccw firmware needs some information in support of the
boot process which is not available on the native machine.
Examples are the netboot firmware load address and now the
boot menu parameters.
While storing that data in unused fields of the IPL parameter block
works, that approach could

- fixup ipl_scsi to use BootMapTable (referred to as Program Table)
- defined value for maximum table entries

1. CKC interrupts can be cleared by resetting the CKC
2. SCLP interrupts can be cleared only via delivery (apart from CPU

So if you have CKC
documenting in qemu-options.hx that s390 treats "splash-time" as the
menu-timeout.
Thoughts?
