Header file asm/fsl_law.h already provides correct definition for second and third PCIe controller (LAW_TRGT_IF_PCIE_2 and LAW_TRGT_IF_PCIE_3). But is missing definition for the first PCIe controller (LAW_TRGT_IF_PCIE_1). Note that existing definition for LAW_TRGT_IF_PCIE_2 and LAW_TRGT_IF_PCIE_3 are slightly complicated, but are really correct for P2020 platform. Signed-off-by: Pali Rohár <pali@kernel.org>
