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.
