arm64: dts: qcom: qrb5165-rb5: fix uSD pins drive strength

Browse Source 
Lower drive strength for microSD data and CMD pins from 16 to 10. This
fixes spurious card removal issues observed on some boards. Also this
change allows us to re-enable 1.8V support, which seems to work with
lowered drive strength.
