soc/intel/common/block/gspi: Add SOC_INTEL_COMMON_BLOCK_GSPI_VERSION_2
Even though kaby lake and cannon lake are using the same GSPI controller, bit meanings (for polarity and state) in SPI_CS_CONTROL register are significantly different. This change provides a new Kconfig option that can be selected by SoCs using these new bit definitions of SPI_CS_CONTROL. Common code takes care of setting the right value for polarity and state field depending upon the version selected by SoC.
