spi: pxa2xx: Use newer more explicit DMAengine terminate API
Commit b36f09c3c441 ("dmaengine: Add transfer termination synchronization support") marked dmaengine_terminate_all() as deprecated and is being replaced by explicit synchronous and asynchronous terminate functions. Here DMA termination are done in two cases: FIFO overrun and module removal. FIFO overrun is handled in interrupt context and converting dmaengine_terminate_all() to dmaengine_terminate_async() does the same than before. Using synchronous termination in module removal however adds a bit more robustness as it waits all completion callbacks have finished. Although it looks all known DMA engines used with spi-pxa2xx don't implement device_synchronize() callback so this too appears to be a no-op in practice.
