Recent version of U-Boot use binman to provide a mechanism for building
images, from simple SPL + U-Boot combinations, to more complex
arrangements with many parts.
This tool uses additional host python modules that must be provided by
Buildroot. So introduce a new option
BR2_TARGET_TI_K3_R5_LOADER_USE_BINMAN to add additional host packages
in U-Boot build dependency to use binman.
When BR2_TARGET_TI_K3_R5_LOADER_USE_BINMAN is set, BINMAN_INDIRS
environment variable to provide the directory to search for binary
blobs and select the packages required by binman. Make sure that
ti-k3-boot-firmware package has been installed before building
ti-k3-r5-loader in order to provide such firmwares.
The BR2_TARGET_TI_K3_R5_LOADER_USE_BINMAN option is currently needed
since we are in the middle of the process to switch TI AM62 and AM64
board defconfig to binman. Keep BR2_TARGET_TI_K3_R5_LOADER_USE_BINMAN
disabled for them until the u-boot/ti-k3-r5-loader version bump to
2024.01.
The dependency of binman is not really easy to follow. First we have
the packages list from binman.rst [1] then we have to install
additional python modules [2]. Maybe in the future it will be
necessary to add host-lzma and host-lz4 in the dependencies list.

- Add missing ti-k3-boot-firmware dependency
Changes in v6:
- Update the commit message adding the links of requirements.
Changes in v5:
- Add dependecy on BR2_PACKAGE_HOST_RUSTC_TARGET_ARCH_SUPPORTS
- Drop runtime dependecies
- Add host-python-pylibfdt dependency without requiring
BR2_TARGET_UBOOT_NEEDS_PYLIBFDT configuration
- Add host-python3 and host-python-setuptools dependencies
- Add SOB and COB tags of Romain Naour
Changes in v4:
- Drop the BR2_TARGET_TI_K3_R5_LOADER_USE_BINMAN option
Changes in v2:
- Change commit message
- Add BR2_TARGET_TI_K3_R5_LOADER_USE_BINMAN option
- Select packages required by binman if
BR2_TARGET_TI_K3_R5_LOADER_USE_BINMAN is enabled
