The stm32-i2s binding inherits from the standard audio-graph-port
schema for its 'port' subnode, audio-graph-port requires the use
of the 'dai-format' property. The stm32mp151c-plyaqm dts file was
using the non-standard name 'format'.

Correct the property name to 'dai-format' to fix the dtbs_check
validation error.

Applied on stm32-next.
