iohub: Add HUB ID for everest systems
Everest's hub id is 0x52, which OPAL earlier didn't recognise:
[ 574.179390090,6] CEC: HUB FRU 0 is CPU Card
[ 574.179430286,6] CEC: 2 chips in FRU
[ 574.179464930,7] CEC: IO Hub Chip #0 OK
[ 574.179497312,7] CEC: PChip: 0 HUB ID: 0052 [EC=0x20] Hub#=0)
[ 574.179543358,3] CEC: Hub ID 0x0052 unsupported ! <--------
Due to not recognising the HUB id, it doesn't initialise the PCI slots.
Define 0x52 as Everest's hub id, so OPAL initialises PCIe slots also for
Everest
