dmaengine: fsl-edma: integrate TCD64 support for i.MX95
In i.MX95's edma version 5, the TCD structure is extended to support 64-bit
addresses for fields like saddr and daddr. To prevent code duplication,
employ help macros to handle the fields, as the field names remain the same
between TCD and TCD64.
Change local variables related to TCD addresses from 'u32' to 'dma_addr_t'
to accept 64-bit DMA addresses.
Change 'vtcd' type to 'void *' to avoid direct use. Use helper macros to
access the TCD fields correctly.
Call 'dma_set_mask_and_coherent(64)' when TCD64 is supported.
