spi-gpio: init CS before spi_bitbang_setup()
spi_bitbang_setup() deasserts the chip select line to initialise
the device. The chip select GPIO line is obtained from
spi_gpio->cs_gpios[] private data.
Currently, devices that are not registered under devicetree
environment will call into spi_bitbang_setup() with stale
cs_gpios[].
This patch ensures spi_gpio->cs_gpios[] is always initialised prior
to calling spi_bitbang_setup().
