Subject: [PATCH 06/10] arm64: dts: qcom: sm6375: Add QUPs and corresponding SPI/I2C hosts
Add necessary nodes to support various QUP configurations. Note that:
- QUP3/4/5 and 11 are straight up missing
- There may be more QUPs physically on the SoC that work perfectly
fine, but Qualcomm decided not to expose them on the downstream kernel
- Many are missing pinctrls, as there are both missing pin funcs in
the TLMM driver and missing configuration settings (though they are
possible to guesstimate quite easily)
