Subject: [PATCH v2 2/6] arm64: dts: qcom: msm8956-loire: Add usb vbus and
 id extcons to ci-hdrc

ci-hdrc does not have the ability to detect voltage presence (5V vbus)
on the USB connector nor the role (via an ID sensing pin), and relies on
the PMIC-side charger to provide such information through an extcon
driver.
