drivers: dma_mcux: Add support for big data transfers 1. Transfers are not limited by XFERCOUNT transfer length of LPC DMA descriptor. Added code to handle block sizes greater than XFERCOUNT. 2. Use the reload_en flag to decide if we should setup a circular descriptor chain. 3. Improve handling of source and destination width. 4. Number of DMA descriptors are defined by a Kconfig value. 5. Changed the dma_reload function to handle transfers greater than XFERCOUNT. Signed-off-by: Mahesh Mahadevan <mahesh.mahadevan@nxp.com>

drivers: dma: Update drivers to use devicetree Kconfig symbol Update DMA drivers to use DT_HAS_<compat>_ENABLED Kconfig symbol to expose the driver and enable it by default based on devicetree. We remove 'depend on' Kconfig for symbols that would be implied by the devicetree node existing. Signed-off-by: Kumar Gala <galak@kernel.org>

Each DMA descriptor can be used to transfer (1024*width) bytes of data.
Increase or decrease this value depending on the max number of data
transferred by the application.
