Julien Olivain db951a4c71 configs/sipeed_licheepi_zero: update Linux, U-Boot to fix build

Since Buildroot commit [1] dc0f7215c6 "package/gcc: switch to 13.x as
default", sipeed_licheepi_zero_defconfig fails when building the Linux
kernel with the error message:

    drivers/ata/libahci.c: In function 'ahci_led_store':
    ./include/linux/compiler.h:350:45: error: call to '__compiletime_assert_1138' declared with attribute error: BUILD_BUG_ON failed: sizeof(_s) > sizeof(long)
      350 |         _compiletime_assert(condition, msg, __compiletime_assert_, __LINE__)

This issue is fixed by upstream Kernel commit [2].

This commit fixes this issue by updating the Linux Kernel from v5.3.5
(which is not a LTS series) to v6.12.43 (which is a LTS series
including the fixes). With this update,
BR2_LINUX_KERNEL_INTREE_DTS_NAME is updated accordingly to follow the
new DTS organization.

This commit also updates U-Boot from 2022.01 to 2025.07. This new
version now requires BR2_TARGET_UBOOT_NEEDS_GNUTLS=y.

While at it, this commit also switches to a stable glibc Bootlin
external toolchain, to follow the new guidelines from [3].

Finally, this commit adds BR2_DOWNLOAD_FORCE_CHECK_HASHES=y and the
corresponding hash files. The .checkpackageignore is also updated to
reflect that change.

Intro
=====

This directory contains a buildroot configuration for building a
LicheePi Zero.

How to build it
===============

Configure Buildroot
-------------------

  $ make sipeed_licheepi_zero_defconfig

Build the rootfs
----------------

Note: you will need to have access to the network, since Buildroot
will download the packages' sources.

You may now build your rootfs with:

  $ make

(This may take a while, consider getting yourself a coffee ;-) )

Result of the build
-------------------

After building, you should obtain this tree:

    output/images/
    +-- boot.scr
    +-- boot.vfat
    +-- rootfs.ext2
    +-- rootfs.ext4 -> rootfs.ext2
    +-- rootfs.tar
    +-- sdcard.img
    +-- sun8i-v3s-licheepi-zero-dock.dtb
    +-- sun8i-v3s-licheepi-zero.dtb
    +-- u-boot.bin
    +-- u-boot-sunxi-with-spl.bin
    `-- zImage

How to write the SD card
========================

Once the build process is finished you will have an image called
"sdcard.img" in the output/images/ directory.

Copy the bootable "sdcard.img" onto an SD card with "dd":

  $ sudo dd if=output/images/sdcard.img of=/dev/sdX

Alternatively, you can use the Etcher graphical tool to burn the image
to the SD card safely and on any platform:

Once the SD card is burned, insert it into your LicheePi Zero board,
and power it up. Your new system should come up now and start a
console on the UART0 serial port.
