ARM: dts: qcom: Set PCIe Wr halt window size to 1GB for sdxlemur

Browse source 
This will set the PCIe Wr halt window size to 1GB and disables BDF halt
for sdxlemur for PINE attach.

In sdxlemur for PINE attaches observed throughput degradation because of 
PCIe latencies, this is due to PCIe write halt window of 1MB and BDF halt
feature enable.
So, disabled BDF halt feature and increased PCIe Wr halt window size to 1GB 
for sdxlemur.
