intel_edison_fab_c.c: let the edison spi driver select the correct method for CS

Browse Source 
Gpio 111 controls the use of hardware CS by the edison kernel's SPI driver.
This is an issue as that CS will go high between every byte transmitted. The
solution is to let gpio 111 alone and let the driver decide what is best. This
fixes #137
