Subject: [PATCH v2 3/3] arm64: dts: qcom: sm6125-seine: Enable GPI DMA 0, QUP 0 and I2C SEs

Enable I2C Serial Engines 1, 2 and 3 which are known to have hardware
connected to them, leaving the rest disabled to save on power.  For
this, only GPI DMA 0 and QUP 0 need to be enabled, as nothing seems to
be connected to Serial Engines on GPU DMA 1 / QUP 1.  Beyond this
downstream only defines a UART console available on Serial Engine 4
which also resides on QUP 0.
