Deprecated configurations around SPI_CS_GPIO

[Olivier-ProGlove]

I was rebasing my Zephyr application on v1.13 RC1 when I noticed warning: SPI_CS_GPIO defined without a type.

Searching into Zephyr code base for the new feature that has been used to replace this configuration shows me there are few platforms (arch/x86/soc/intel_quark, boards/arc/arduino_101_sss, boards/x86/arduino_101) and SPI options (SPI_n_CS_GPIO_PORT and SPI_n_CS_GPIO_PIN) depending on this non-existing KConfig option.

I guess it should be fixed/cleaned for v1.13.

I am not sure if SPI_CS_GPIO, SPI_n_CS_GPIO_PORT and SPI_n_CS_GPIO_PIN can be simply removed.

Looks like we've removed these so closing this issue. Please re-open if I missed something.
