ARM: dts: qcom: drop apq8084 support

APQ8084 is one of the platforms which gained very little interest
upstream. It doesn't look like the there was any interest in these
devices since December 2019. Two devices supported upstream have very
minumal DT files. Start forgetting about the platform by
removing DT files.
