kbuild: determine the output format of DTC by the target suffix
cmd_dtc takes the additional parameter $(2) to select the target format, dtb or yaml. This makes things complicated when it is used with cmd_and_fixdep and if_changed_rule. I actually stumbled on this. See commit 3d4b2238684a ("kbuild: fix DT binding schema rule again to avoid needless rebuilds"). Extract the suffix part of the target instead of passing the parameter. Fortunately, this works for both $(obj)/%.dtb and $(obj)/%.dt.yaml . Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
