Subject: [PATCH v2 4/6] arm64: dts: qcom: msm8916-motorola: Use UART1
 console pinctrl

The Motorola MSM8916-based smartphones all use UART1 with 2 pins (TX, RX)
as debug UART console, so make use of the new &blsp_uart1_console_default
template. This applies the needed bias-pull-up to avoid garbage input,
bootph-all for U-Boot and avoids having to override the UART pins.
