Subject: [PATCH v3 2/3] irqchip: LAN966X_OIC should depend on 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.

Fixes: 3e3a7b35332924c8 ("irqchip: Add support for LAN966x OIC")

v3:
  - Fix symbol name in one-line summary,
  - Add Acked-by,

v2:
  - Drop dependency on SOC_LAN966, as the OIC is used only in LAN966x
    PCI endpoint mode,
  - Replace MFD_LAN966X_PCI by MCHP_LAN966X_PCI, as the latter is the
    symbol that ended upstream.
