Romain Naour 356c092389 configs/am574x_idk_defconfig: bump linux to 6.18.16 and u-boot to 2026.04
This commit:
  - updates the Kernel from LTS 6.6.14 to 6.18.16
  - updates U-Boot from 2024.01 to 2026.04
  - switches to Bootlin external glibc stable toolchain
  - enable BR2_DOWNLOAD_FORCE_CHECK_HASHES=y, add custom hashes stored
    in BR2_GLOBAL_PATCH_DIR="board/ti/am574x-idk/patches" and removes
    the exception entry in .checkpackageignore.
  - enable BR2_LINUX_KERNEL_DTB_KEEP_DIRNAME=y to install the board
    devicetree in the boot (vfat) partition keeping the directory
    prefixes (ti/omap/am574x-idk.dtb). u-boot nowadays is looking for
    boards devicetree using such directory prefixes [1].
    Update genimange.cfg file accordingly.
  - While at it, add a label to the boot (vfat) partition to not use a
    generated label.
  - set BR2_TARGET_ROOTFS_EXT2_SIZE="256M" since the rootfs no longer
    fit in the default size (60M).
  - Remove the rootfs partition predefined 1G size to avoid a parted
    warning about "unallocated space within the partition."
  - Update extlinux.conf kernel command line to use "console=ttyS2"
    instead of "ttyS0". Seems a typo introduced with the defconfig
    (AM57xx always used ttyS2 as kernel console).
