arm64: dts: qcom: sc7180-trogdor: Simplify spi0/spi6 labeling
We had to do this spi0/spi6 flip-flop on trogdor-r0 because the spi
buses got swizzled between r0 and r1. The swizzle stopped after r1, but
we kept this around to support either hardware possibility and to keep
trogdor-r0 working.
trogdor-r0 isn't supported upstream, so this swizzle is not doing
anything besides making a pattern that others tryt to copy for the EC and
H1 nodes. Let's remove it and simplify the dts files.
