meson: Introduce target-specific Kconfig Add a target-specific Kconfig. We need the definitions in Kconfig so the minikconf tool can verify they exits. However CONFIG_FOO is only enabled for target foo via the meson.build rules. Two architecture have a particularity, ARM and MIPS. As their translators have been split you can potentially build a plain 32 bit build along with a 64-bit version including the 32-bit subset.

kconfig: express dependency of individual boards on libfdt Now that boards are enabled by default and the "CONFIG_FOO=y" entries are gone from configs/devices/, there cannot be any more a conflicts between the default contents of configs/devices/ and a failed "depends on" clause. With this change, each individual board or target can express whether it needs FDT. It can then include the common code in the build via "select DEVICE_TREE", which will also as tell meson to link with libfdt. This allows building non-microvm x86 emulators without having libfdt available.
