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.
