dt-bindings: dma: fsl-edma: Add fsl-edma.h to prevent hardcoding in dts
[ Upstream commit 1e9b05258271b76ccc04a4b535009d2cb596506a ]
Introduce a common dt-bindings header file, fsl-edma.h, shared between
the driver and dts files. This addition aims to eliminate hardcoded values
in dts files, promoting maintainability and consistency.
DTS header file not support BIT() macro yet. Directly use 2^n number.
