configs/ti_am62x_sk_defconfig: bump U-Boot version to 2024.01

The 2024.01 version of U-Boot for the am62x-sk board has introduced two
major changes:
- The device tree k3-am625-sk.dtb is no longer searched in /boot, but in
  /boot/dtb/ti. Hence, the disabling of BR2_LINUX_KERNEL_INSTALL_TARGET
  and the use of extlinux.conf for the proper loading of the device tree.
  Furthermore, the parameter BR2_ROOTFS_POST_SCRIPT_ARGS was used to
  auto-generate the extlinux.conf file so that developers can change the
  kernel loading options by modifying the .config.
- U-Boot is capable of building tiboot3.bin using Binman. So it's no longer
  necessary to use custom tools like ti-k3-image-gen.
- Use a custom tiboot3.bin since the default is "hs-fs",
  but the ti_am62x_sk_defconfig expect the "gp" one

Tested on SK-AM62B-P1.
