Subject: [PATCH] dt-bindings: i2c: Describe SA8255p

Add DT bindings for the QUP GENI I2C controller on sa8255p platforms.

SA8255p platform abstracts resources such as clocks, interconnect and
GPIO pins configuration in Firmware. SCMI power and perf protocol
are utilized to request resource configurations.

SA8255p platform does not require the Serial Engine (SE) common properties
as the SE firmware is loaded and managed by the TrustZone (TZ) secure
environment.
