Hello build bot (Jenkins), Arthur Heymans, Timothy Pearson, Ron Minnich,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/57082

to look at the new patch set (#17).

Change subject: src/mainboard/emulation/qemu-power9: require hb-mode=on
......................................................................

src/mainboard/emulation/qemu-power9: require hb-mode=on

"hb-mode" is a -machine flag for QEMU. "hb" stands for Hostboot, which
is OpenPower firmware created by IBM.

QEMU for PPC64 can run initial program in two different modes:
 * hb-mode=off with load address 0x00000000
 * hb-mode=on with load address 0x08000000

Real hardware always loads firmware at 0x08000000 and coreboot shouldn't
require a special build to be run on QEMU.

Memory layout is updated to reflect change of load address.
