codecs: wcd_spi: do not use on-stack memory for any transfers Currently, for some small (1/4/8 bytes) transfers, the driver uses on-stack memory to perform the transfer. This is not safe as the underlying master/dma driver could try to map/dma this memory. Change makes sure to never use on-stack memory for any transfers.
