board/aarch64: styx: rename second green led and drop second sfp led

On Rev. B, the second LED on the copper ports is green instead of yellow.
This patch renames them from yellow -> aux => <device>:aux:tp

Also on Rev. B, the second LED for SFP ports do not work at all.  This
patch drops them from the device tree to avoid confusion.
