[PATCH 0/3] kbuild: Add wilddt function instead of listing dtbs

[Leonard Crestez <leonard.crestez@nxp.com>]

The dts makefiles go through a lot of pointless churn when boards are
added. Many SOCs (such as imx) have very simple naming conventions for
all boards using a certain chip and board listings can be easily
collapsed using wildcards.

Add a "wilddt" function and use it for imx6/7/8 and layerscape. This can
be applied to many other soc families later.

Previously sent as RFC: https://lore.kernel.org/patchwork/patch/1022737/

Changes since RFC:
 * Split into 3-part series
 * Move the wilddt to Kbuild.include so that it's available everywhere
 * Use $(srctree)/$(src) instead of $(dtstree)
 * Also use wilddt in arm64/boot/dts/freescale

Series is against next-20190107, conflicts are to be expected as board
list keeps changing.

  kbuild: Add wilddt function
  ARM: dts: imx: Use wilddt function
  arm64: dts: freescale: Use wilddt function
