I tested this on a google,lazor-rev5-sku6 (your code correctly found
bpc as 6) and a google,coachz-rev2-sku0 (your code correctly found bpc
as 8).

As an extra safety net, I also double-checked that the generic
edp-panel would work. I also hacked the first device to use
"edp-panel" as a compatible string, found the panel to be detected,
and found bpc was properly found as 6.

So from a testing perspective this seems good.
