This series adds GPI DMA support for the sc8280xp platform. This option is
required only on devices where the touch panel is connected over SPI.

base-commit: 58ba80c4740212c29a1cf9b48f588e60a7612209

Changes in v3:
- fix shifted dma channels
- do not enable this on devices without connected SPI slave devices.
- Link to v2: https://lore.kernel.org/linux-arm-msm/20250612075724.707457-1-mitltlatltl@gmail.com

Changes in v2:
- document dt-bindings (Dmitry)
- use describe in commit message (Eugen)
- enable it for sc8280xp based devices
- Link to v1: https://lore.kernel.org/linux-arm-msm/20250605054208.402581-1-mitltlatltl@gmail.com

SPI on SC8280XP requires DMA (GSI) mode to function properly. Without it,
SPI controllers fall back to FIFO mode, which causes:

[    0.901296] geni_spi 898000.spi: error -ENODEV: Failed to get tx DMA ch
[    0.901305] geni_spi 898000.spi: FIFO mode disabled, but couldn't get DMA, fall back to FIFO mode
...
[   45.605974] goodix-spi-hid spi0.0: SPI transfer timed out
[   45.605988] geni_spi 898000.spi: Can't set CS when prev xfer running
[   46.621555] spi_master spi0: failed to transfer one message from queue
[   46.621568] spi_master spi0: noqueue transfer failed
[   46.621577] goodix-spi-hid spi0.0: spi transfer error: -110
[   46.621585] goodix-spi-hid spi0.0: probe with driver goodix-spi-hid failed with error -110

Therefore, add GPI DMA controller nodes for qup{0,1,2}, and add DMA
channels for SPI and I2C, UART is excluded for now, as it does not
yet support this mode.

Note that, since there is no public schematic, this configuration
is derived from Windows drivers. The drivers do not expose any DMA
channel mask information, so all available channels are enabled.
