spi: dw: Set GPIO_SS flag to toggle Slave Select on GPIO CS
The Designware SPI master requires slave selection before the transfer
can begin [1].
This patch uses the new master flag to indicate both the GPIO CS and
the internal chip select should be used.
Tested On:
Altera CycloneV development kit
Compile tested for build errors on x86_64 (allyesconfigs)
[1] DesignWare dw_apb_ssi Databook, Version 3.20a (page 39)
