EFTracking FPGA Integration: Fix output validation histograms

Maxwell Cuirequested to merge
zhcui/athena:fix-histo into main

This MR removes some mistakenly added histograms. The strip cluster doesn't have local position y and the dimension of the accssor should be 1 instead of 2.

This package is a standalone WIP and this MR will not affect production and validation workflow.
