Convert the majority of MSM8916/39-based boards, which use UART2 with 2 pins (TX, RX) for the debug UART console. This adds the needed bias-pull-up and bootph-all properties to avoid garbage input when UART is disconnected. apq8016-schneider-hmibsc.dts does not use UART2 as a debug console, so it's left as-is in this commit.
