[PATCH 1/1] SPI: dw_spi, fix PPC build

[Jiri Slaby <jslaby@suse.cz>]

Currently, build on PPC dies with:
In file included from drivers/spi/dw_spi_mmio.c:16:
include/linux/spi/dw_spi.h:147: error: field ‘tx_sgl’ has incomplete type
include/linux/spi/dw_spi.h:149: error: field ‘rx_sgl’ has incomplete type

Add linux/scatterlist.h include to dw_spi.h, because we need to know
the contents of the structure.
