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.
BUG=b:195943311
TEST=boot majolica & guybrush, verify spi settings
