spi: meson-spicc: add DMA support
Add DMA support for spicc driver.
DMA works if the transfer meets the following conditions:
1. 64 bits per word;
2. The transfer length must be multiples of the dma_burst_len,
and the dma_burst_len should be one of 8,7...2,
otherwise, it will be split into several SPI bursts.
