powerpc: pci-ioda: Fix the stale irq chip reference
The commit f0ac60e6e311 ("powerpc/powernv/pci: Switch to use
msi_create_parent_irq_domain()") removed the legacy MSI irq chip
pnv_pci_msi_irq_chip but left behind the static definition of it and
its reference in is_pnv_opal_msi().
The KVM IRQ bypass for vfio devices is broken because the
comparision in is_pnv_opal_msi() fails on the comparision with
stale unused variable showing the below errors in dmesg.
kvmppc_set_passthru_irq_hv: Could not assign IRQ map for (X,Y)
kvmppc_set_passthru_irq (irq X, gsi Y) fails: -2
vfio-pci A:B:C.D irq bypass producer (eventfd Z) registration fails: -2
The patch removes the stale variable definition and fixes the
is_pnv_opal_msi() by comparing against the chip name prefix.
