[Skiboot] [PATCH v4 5/6] iohub: Add HUB ID for everest systems

[Mahesh Salgaonkar]

From: Aditya Gupta <adityag at linux.ibm.com>

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
