vc/amd/opensil/genoa_poc/mpio: don't add duplicate MPIO descriptors
When the device right below the MPIO chip driver has downstream devices
without another chip in between, those downstream devices will also have
their chip_ops entry set to vendorcode_amd_opensil_genoa_poc_mpio_ops.
To avoid adding the same MPIO descriptor again for those additional
downstream devices, make sure that the chip_info pointer of the device
isn't the same as the one of the parent device, since that's only the
case for those additional downstream devices.
TEST=Onyx still boots to the payload and the MPIO configuration reported
from the openSIL code is still the same
