dt-bindings: qcom: se-common: Add QUP Peripheral-specific properties for I2C, SPI, and SERIAL bus

Introduce a new YAML schema for QUP-supported peripherals. Define common
properties used across QUP-supported peripherals.

Add property `qcom,enable-gsi-dma` to configure the Serial Engine (SE) for
QCOM GPI DMA mode.

Reference the common schema YAML in the GENI I2C, SPI, and SERIAL YAML
files.

+
+description:
+  The Generic Interface (GENI) based Qualcomm Universal Peripheral (QUP) is
+  a programmable module that supports a wide range of serial interfaces
+  such as UART, SPI, I2C, I3C, etc. This defines the common properties used
+  across QUP-supported peripherals.
