phy: PHY_LAN966X_SERDES should depend on SOC_LAN966 || MCHP_LAN966X_PCI

The Microchip LAN966X SerDes PHY is only present on Microchip LAN966x
SoCs.  However, when used as a PCI endpoint, all peripherals of the
LAN966x SoC can be accessed by the PCI host.  Hence add dependencies on
SOC_LAN966 and MCHP_LAN966X_PCI, to prevent asking the user about this
driver when configuring a kernel without Microchip LAN966x SoC and PCIe
support.
