[RESEND PATCH] spi: atmel: Fix DMA-setup for transfers with more than 8 bits per word

[Nicolas Ferre]

From: David Mosberger-Tang <davidm at egauge.net>

The DMA-slave configuration depends on the whether <= 8 or > 8 bits
are transferred per word, so we need to call
atmel_spi_dma_slave_config() with the correct value.
