arm64: dts: qcom: sc8280xp-microsoft-arcata: set GPI DMA channels
It's found that some GPI interfaces shouldn't be touched by HLOS,
otherwise system hang / reset happens.
The GPI interface availability information is available via the ACPI
DSDT table, as interrupt resources for \_SB_.QGP* devices.
Add such information to the device tree file.
The DSDT table is acquired at [1].
