Can we get rid of this node swap now? I think it is only around because
early on we swapped the EC and H1 spi interfaces and then we had to swap
it every time we made a new board.

$ git grep ap_ec_spi
arch/arm64/boot/dts/qcom/sc7180-trogdor-coachz.dtsi:ap_ec_spi: &spi6 {};
arch/arm64/boot/dts/qcom/sc7180-trogdor-lazor.dtsi:ap_ec_spi: &spi6 {};
arch/arm64/boot/dts/qcom/sc7180-trogdor-pompom.dtsi:ap_ec_spi: &spi6 {};
arch/arm64/boot/dts/qcom/sc7180-trogdor-r1.dts:ap_ec_spi: &spi6 {};

It feels like we'd be better off leaving that quirk in trogdor-r0, which
conveniently isn't upstream, and then relabel the spi nodes in
sc7180-trogdor.dtsi now. Otherwise I look at this and have to remember
that whenever this dtsi file is included, we've already included the
sc7180.dtsi file before it, so that the relabel actually works.
