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_UBOOT_USE_BINMAN to
add additional host packages in U-Boot build dependency to use binman.

The binman requirement is directly included in buildman dependency
(tools/buildman/requirements.txt) since within U-Boot, binman is
invoked by the build system, here buildman [1].

Furthermore, the use of Binman no longer makes it necessary to set
`UBOOT_MAKE_OPTS += DM=...'. We had the explanation from [2]:

BINMAN_INDIRS is used to fetch the DM binary from <path to
ti-linux-firmware>/ti-dm/ and SYSFW binaries from <path to
ti-linux-firmware>/ti-sysfw/.

Changes in v7:
- Replace ifneq ($(BR2_TARGET_UBOOT_USE_BINMAN),y) with
  ifeq ($(BR2_TARGET_UBOOT_USE_BINMAN),).
- Update the commit message

Changes in v6:
- BR2_TARGET_UBOOT_USE_BINMAN
- Binman tool is not specific to TI K3 platform, so add an option to specify
  the use of Binman in U-Boot.
- Add runtime dependencies
- Update commit message
- Add SOB and COB tags of Romain Naour

Changes in v5:
- Drop "DM=$(BINARIES_DIR)/ti-dm/$(UBOOT_TI_K3_DM_SOCNAME)/ipc_echo_testb_mcu1_0_release_strip.xer5f"
  from UBOOT_MAKE_OPTS.
