soc/amd/common/block/spi: Add support for common SPI configuration
This change adds support for following SPI configuration functions to common block SPI driver and exposes them to be used by SoC: 1. fch_spi_early_init(): Sets up SPI ROM base, enables SPI ROM, enables prefetching, disables 4dw burst mode and sets SPI speed and mode. 2. fch_spi_config_modes(): This allows SoC to configure SPI speed and mode. It uses SPI settings from soc_amd_common_config to configure the speed and mode. These functions expect SoC to include soc_amd_common_config in SoC chip config and mainboard to configure these settings in device tree.
