[Buildroot] [PATCH v2 0/4] beaglev: enable opensbi generic platform

[Drew Fustini]

Introduce BR2_TARGET_UBOOT_FORMAT_DTB to copy u-boot.dtb [1] to
BINARIES_DIR. This file can be used for FW_FDT_PATH [2] in OpenSBI build
when BR2_TARGET_OPENSBI_FW_FDT_PATH is enabled.

Update U-Boot in beaglev_defconfig to new commit in starfive-tech repo
which enables CONFIG_OF_SEPARATE to build u-boot.dtb [3]. Finally switch
to upstream OpenSBI repo and use generic platform now that it supports
the console UART [4] on the BeagleV Starlight JH7100 board.

- added Reviewed-by: for Bin Meng and Alistair Francis
