vc/amd/opensil/genoa_poc: move configure_mpio call to setup_opensil

Instead of calling configure_mpio from the init function of the MPIO
chip struct for the first device that has this struct as chip_ops, call
if from setup_opensil. This will allow to do the calls into openSIL from
the SoC's chip_ops init function instead of having to rely on boot state
hooks. configure_mpio needs to be called after the xSimAssignMemoryTp1
call which sets up the openSIL data structures, but before the
opensil_entry(SIL_TP1) call for which the MPIO data structures need to
be filled for it to be able to initialize the hardware accordingly.
Since the vendorcode_amd_opensil_genoa_poc_mpio_ops struct now no longer
assigns configure_mpio to the init function pointer, we have to check
if the device's chip_ops pointer points to
vendorcode_amd_opensil_genoa_poc_mpio_ops instead of checking if the
chip_ops' init function is configure_mpio to match for the devices below
the MPIO chips in the devicetree.

TEST=Onyx still boots to the payload and the MPIO configuration reported
from the openSIL code is still the same
