ppc/pnv: Add pca9552 to powernv10-rainier for PCIe hotplug power control

The Power Hypervisor code expects to see a pca9552 device connected
to the 3rd PNV I2C engine on port 1 at I2C address 0x63 (or left-
justified address of 0xC6).  This is used by hypervisor code to
control PCIe slot power during hotplug events.
