soc/intel/common: prepare for lpss clock split
Apparently Intel had decided to use different clock speeds for
some of its IP blocks in some of its designs. The i2c designware driver
has already been moved into common code allowing for its own Kconfig
value. That currently leaves SPI (UART isn't using the clock currently).
Therefore, remove SOC_INTEL_COMMON_LPSS_CLOCK_MHZ and add
SOC_INTEL_COMMON_BLOCK_GSPI_CLOCK_MHZ to allow for the different clock
speeds present in the system for the various IP blocks.
