dt-bindings: dma: snps,dw-axi-dmac: Add compatible string for Agilex5

Browse Source 
The address bus on Agilex5 is limited to 40 bits. When SMMU is enable this
will cause address truncation and translation faults. Hence introducing
"altr,agilex5-axi-dma" to enable platform specific configuration to
configure the dma addressable bit mask.

Add a fallback capability for the compatible property to allow driver to
probe and initialize with a newly added compatible string without requiring
additional entry in the driver.
