According to specification the SPI1 has 5 bits for chip selects. The current
code limits it to 4 bits. The patch fixes that constant.

Fixes: 7063c0d942a1 (spi/dw_spi: add DMA support)

I'm not seeing this as an obvious candidate for stable, it seems more
like a new feature really in terms of impact, and that doesn't look like
the commit that's being fixed - it's the last one that refactored things
but that's not the same thing.
