[PATCH v2 1/2] spi: use dmaengine public API instead of raw ops

[Frank.Li@oss.nxp.com]

From: Frank Li <Frank.Li@nxp.com>

Replace direct calls to the internal DMA device ops
device->device_issue_pending() with the proper public DMA engine wrappers:
dma_async_issue_pending().

Drivers must not call device ops directly; the wrappers provide locking,
debug checks, and a stable interface that hides internal implementation
details of the DMA controller driver.
