amd/common/block/spi: Add EFS SPI configurations to Kconfig
The Embedded Firmware Structure should contain SPI speed, mode
and Micron support for the PSP to program. Add Kconfig options
to specify these values to use for future platform changes.
BUG=b:158755102
TEST=Test menuconfig and platform build for Trembyle and Mandolin.
