The ROHM BU27008 is a sensor with 5 photodiodes (red, green, blue, clear
and IR) with four configurable channels. Red and green being always
available and two out of the rest three (blue, clear, IR) can be
selected to be simultaneously measured. Typical application is adjusting
LCD backlight of TVs, mobile phones and tablet PCs.
Add BU27008 dt-bindings.

Filename like compatible, so rohm,bu27008.yaml

Does not look like you tested the bindings. Please run `make
dt_binding_check` (see
Documentation/devicetree/bindings/writing-schema.rst for instructions).

Thanks Krzysztof. I should've remembered this as you told me the same
thing during the bu27034 review. Feel free to kick me atthe ELC-E if I
do the same mistake with bu27010 as well ^^;

I actually did. But I did first run the dt_binding_check without
filename - causing it to check all the in-tree bindings - which took a
while. So, I went to have a lunch. When I came back I re-ran the check
with the filename (DT_SCHEMA_FILES=...) - which gave me no errors.
I _assume_ this is because running the check for all bindings had
already done <add step here> generating the warning, while re-running
the check with the filename omitted the <add step here> and no longer
displayed the warning.
In any case, I missed warning from full-check, and checker missed the
warning when re-ran.
