Rob Herring f858927fd6 scripts/dtc: Update to upstream version v1.4.7-14-gc86da84d30e4
Major changes are I2C and SPI bus checks, YAML output format (for
future validation), some new libfdt functions, and more libfdt
validation of dtbs.

The YAML addition adds an optional dependency on libyaml. pkg-config is
used to test for it and pkg-config became a kconfig dependency in 4.18.

This adds the following commits from upstream:
