Enable CONFIG_QCOM_FIT_MULTIDTB and CONFIG_OF_LIBFDT_OVERLAY by default for Qualcomm Snapdragon platforms to provide automatic DTB selection from qclinux_fit.img with overlay support.
This allows U-Boot to automatically select the appropriate device tree based on hardware parameters detected from SMEM, improving boot compatibility across different hardware variants and reducing the need for board-specific DTB selection logic. Additionally, configure platform-specific IMEM sizes required for storage type detection: - QCM6490 and QCS615: 0x2B000 - QCS9100: 0x59000 The IMEM size configuration enables proper shared IMEM cookie access for boot device type detection (UFS/eMMC/NAND), which is essential for the FIT multi-DTB selection process.
