ARM: dts: qcom: Set PCIe Wr halt to 1GB and disable BDF halt for sdxlemur

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

In sdxlemur for HSP CPE attaches observed throughput degradation due to
PCIe latencies with default PCIe write halt window of 1MB and BDF halt
feature enable.
So, increased PCIe Wr halt window size to 1GB and disabled
BDF halt for sdxlemur.
