ARM64: zynqmp: Add support for chip ID detection
Chip ID needs to be known for loading bitstream because U-Boot checks ID from bitstream header in BIT format. BIN format is completely unchecked. The chipid is get from ATF via SMC. Signed-off-by: Siva Durga Prasad Paladugu <sivadur@xilinx.com> Signed-off-by: Michal Simek <michal.simek@xilinx.com>
