Subject: [PATCH 1/2] kbuild: use separate commands for generating *.dtb and *.dt.yaml

Currently, cmd_dtc takes $(2) to select the target format. The
additional parameter complicates things when it is used with
cmd_and_fixdep and if_changed_rule.

To make it easier to understand, use a separate cmd_dtc_yaml.

One visible change is, 'DTCYAML' is used for the log when compiling
*.dts to *.dt.yaml.
