[RFC PATCH v2 5/5] arm64: dts: qcom: sc7180: Add sc7180-trogdor.fitconfig FIT config file

[Douglas Anderson]

Add a FIT configuration file (`sc7180-trogdor.fitconfig`) listing the
SC7180 Trogdor family board DTBs, allowing the LZ4-compressed Trogdor
FIT image to be built with:

  make \
    FIT_CONFIG=qcom/sc7180-trogdor.fitconfig \
    FIT_COMPRESSION=lz4 \
    FIT_FACTOR_DTBS=1 \
    image.fit

Having an in-tree `.fitconfig` configuration file for Trogdor produces a
FIT image matching what downstream ChromeOS build scripts
programmatically generate, makes it easy to use `fdtfactor` on the
Trogdor kernel image, serves as a template for future Chromebooks (which
could encode board/SKU matching metadata in configuration match subnodes
rather than combinatorial `compatible` strings), and helps community
users building upstream kernels for `sc7180-trogdor` devices.

As mentioned in the cover letter, there is no desperate need to land
this. If it's controversial or people hate it then it's fine not to
land it.

Changes in v2:
- Replace 728-line sc7180-trogdor.its with a 49-line
  sc7180-trogdor.fitconfig sidecar file consumed by scripts/make_fit.py
  (Simon Glass)
- Move motivation for sc7180-trogdor from commit notes into the commit
  message body (Simon Glass)
