Remove duplicate ro.bq.gpu_to_cpu_unsupported=1
We had in our device tree now
ro.bq.gpu_to_cpu_unsupported=1 and
ro.bq.gpu_to_cpu_unsupported=true
The ro.bq.gpu_to_cpu_unsupported=true has a clearer description
and the definition of those two configurations are the same so
we decided to remove ro.bq.gpu_to_cpu_unsupported=1
