Support for Buildroot 2024.02

[kobayutapon]

Modified to work with Buildroot 2024.02.

• Changed Kernel to 6.1.x series.
• Fixed to start getty service when systemd is selected.
• Removed u-boot patch.

I tested this and it doesn't seem to work completely - build is ok, startup is OK. But when trying to install a rauc update I get the error below:

# rauc install rootfs.raucb

LastError: Failed mounting bundle: Failed to open /dev/mapper/control: No such file or directory

Does this work on your setup?

Sorry, I didn't check enough. I will check the symptoms you pointed out and send another pull request.

It seems we now need to specify all these items in linux.fragment:

CONFIG_MD=y
CONFIG_BLK_DEV_DM=y
CONFIG_BLK_DEV_LOOP=y
CONFIG_DM_VERITY=y
CONFIG_SQUASHFS=y
CONFIG_CRYPTO_SHA256=y

This is in line with the rauc docs: https://rauc.readthedocs.io/en/latest/integration.html#kernel-configuration

I checked the operation and committed the fix. Thanks for pointing this out.
