[PATCH 2/6] arm64: dts: qcom: sm8250: Rename UART2 node to UART12

[Manivannan Sadhasivam]

The UART12 node has been mistakenly mentioned as UART2. Let's fix that
for both SM8250 SoC and MTP board and also add pinctrl definition for
it.

Fixes: 60378f1a171e ("arm64: dts: qcom: sm8250: Add sm8250 dts file")
