The U-Boot part of the defconfig was not specifying explicitly any
U-Boot version. Since commit
21e3ae8a18bb77943c0a2492ab9ebf14cab333f9
("boot/uboot: default to kconfig buildsystem for latest version"), we
default to using the kconfig build system when the default U-Boot
version is used. Following this change, the apf27 defconfig therefore
started using kconfig, for which the BR2_TARGET_UBOOT_BOARDNAME
Config.in option is not used. Due to this, the build fails with:
boot/uboot/uboot.mk:411: *** No board defconfig name specified, check your BR2_TARGET_UBOOT_BOARD_DEFCONFIG setting. Stop.
Indeed, when Kconfig is used, the board defconfig must be specified
with BR2_TARGET_UBOOT_BOARD_DEFCONFIG.
As part of fixing this, we also set a fixed U-Boot version for this
defconfig, like we do in all other defconfigs.
