soc/amd/common/block/spi: Add SPI config to Kconfig
Currently, The SPI speed/mode configuration is split between Kconfig and devicetree. We'd like to have everything in one place. Since we need the fast-read speed and the mode available in the Makefile to build the AMD EFS table, we currently need it in Kconfig. Move all of the settings to Kconfig and remove them from Devicetree in a later commit.
