[Buildroot] [PATCH] configs/mx6udoo: update U-Boot and kernel

[Fabio Estevam]

Update to U-Boot 2024.07 and kernel 6.10.6 versions.

As kernel 6.10 fixes the USB kernel hang, remove the original patch.

Also convert it to use extlinux.conf file.

-[PATCH] ARM: dts: imx6qdl-udoo: Disable usbh1 to avoid kernel hang
-
-Currently the kernel hangs when USB Host1 is enabled due to the lack of
-support for controlling the USB hub clock and GPIO reset line.
-
-Peter Chen has made several attempts to fix this problem, but his series
-has not been applied yet, so better disable USB host1 for now to avoid
-the kernel hang.

Applied to next. You had forgotten to update .checkpackageignore, which
was referencing a patch that you are removing here.

Also, while you're working on this defconfig, what about enabling
BR2_DOWNLOAD_FORCE_CHECK_HASHES=y ?

Thanks a lot!

Thomas
