Add a PCI driver that handles the LAN966x PCI device using a device-tree overlay. This overlay is applied to the PCI device DT node and allows to describe components that are present in the device. The memory from the device-tree is remapped to the BAR memory thanks to "ranges" properties computed at runtime by the PCI core during the PCI enumeration. The PCI device itself acts as an interrupt controller and is used as the parent of the internal LAN966x interrupt controller to route the interrupts to the assigned PCI INTx interrupt.
