Stephen Boyd 372b2aee97 arm64: dts: qcom: Remove duplicate sc7180-trogdor include on lazor/homestar
The sc7180-trogdor-{lazor,homestar}-*.dtsi files all include
sc7180-trogdor.dtsi and sc7180-trogdor-lazor.dtsi or
sc7180-trogdor-homestar.dtsi, so including it here in the
sc7180-trogdor-{lazor,homestar}.dtsi file means we have a duplicate
include after commit 19794489fa ("arm64: dts: qcom: Only include
sc7180.dtsi in sc7180-trogdor.dtsi"). We include the sc7180-trogdor.dtsi
file in a board like sc7180-trogdor-lazor-r1.dts so that we can include
the display bridge snippet (e.g. sc7180-trogdor-ti-sn65dsi86.dtsi)
instead of making ever increasing variants like
sc7180-trogdor-lazor-ti-sn65dsi86.dtsi.

Unfortunately, having the double include like this means the display
bridge's i2c bus is left disabled instead of enabled by the bridge
snippet. Any boards that use the i2c bus for the display bridge will
have the bus disabled when we include sc7180-trogdor.dtsi the second
time, which picks up the i2c status="disabled" line from sc7180.dtsi.
This leads to the display not turning on and black screens at boot on
lazor and homestar devices.

Fix this by dropping the include and making a note that the
sc7180-trogdor-{lazor,homestar}.dtsi file must be included after
sc7180-trogdor.dtsi
