ARM64: zynqmp: Read RAM information from DT
Read information about memory from DT. This patch simplify life with synchronization between DT and board files. dram_init() only needs maximum RAM size below 4GB that's why please sort banks in memory node. dram_init_banksize() copies memory setup to bi_dram[]. This will avoid reading information from DT twice. Memory test start/end were changed to DDR location to let memtest still compiled. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
