Subject: [PATCH 7/8] arm64: dts: qcom: apq8039-t2: Move customized pinctrl
 to board

Prepare for removing the generic UART pinctrl templates from msm8939.dtsi
by copying the definition for the 4 pin UART1 instance into apq8039-t2.dts
and apply the override to limit it to 2 pins. Having it defined separately
in the board DT file makes it clear that the set of pins/pull etc are
specific to the board and UART use case.

No functional change.
