DT law_trgt_if property defines Local Access Window Target Interface. Local Access Window Target Interface is used for identifying individual peripheral and mapping its memory to CPU. Interface id is defined by hardware itself. U-Boot uses law_trgt_if DT property in PCIe nodes for configuring memory mapping of individual PCIe controllers. Linux kernel fsl_pci.c driver currently does not touch Local Access Window and expects that U-Boot configures it properly. Add law_trgt_if property to PCIe DT nodes for P2020. This allows usage of kernel P2020 PCIe DT nodes in U-Boot. And therefore allows to share P2020 DTS files between Linux kernel and U-Boot.
