irqchip/lan966x-oic: Make CONFIG_LAN966X_OIC depend on CONFIG_MCHP_LAN966X_PCI

The Microchip LAN966x outband interrupt controller is only present on
Microchip LAN966x SoCs, and only used in PCI endpoint mode.  Hence add a
dependency on MCHP_LAN966X_PCI, to prevent asking the user about this
driver when configuring a kernel without Microchip LAN966x PCIe support.
