Due to licensing issues, the files ps7_init.c/h are not able to be distributed with U-Boot source code. Recent Xilinx tools also provide the GPL variants (ps7_init_gpl.c/h), compatible with U-Boot license. Prior to this commit, we had to copy ps7_init files into board/xilinx/zynq/ before the compile. To be more user-friendly, let's include ps7_init_gpl.c/h for Zedboard, MicroZed, ZC702, ZC706. These init code have been taken from the hwplatform_templates directory of Xilinx SDK 2014.4. You can still use customized ps7_init_gpl.c/h by enabling CONFIG_ZYNQ_CUSTOM_INIT. The recommended directory for storing them is now board/xilinx/zynq/custom_hw_platform, but board/xilinx/zynq is still supported for backward compatibility. The latter emits a warning message to prompt users to gradually switch to the new directory.
