Stephan Gerhold 80816ea7c3 arm64: dts: qcom: msm8916: Pull down PDM GPIOs during sleep
[ Upstream commit e2ee9edc282961783d519c760bbaa20fed4dec38 ]

The original qcom kernel changed the PDM GPIOs to be pull-down
during sleep at some point. Reportedly this was done because
there was some "leakage at PDM outputs during sleep":

I cannot say how effective this is, but everything seems to work
fine with this change so let's apply the same to mainline just
to be sure.
