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. Cc: "Joseph S.
