arm64: dts: qcom: ipq6018: Add/remove some newlines

Some lines were broken very aggresively, presumably to fit under 80 chars
and some places could have used a newline, particularly between subsequent
nodes. Address all that and remove redundant comments near PCIe ranges
while at it so as not to exceed 100 chars needlessly.
