mb/google/kahlee/Kconfig: add remaining SPI speed settings

Before this patch only the SPI settings that will also end up in the
amdfw part of the firmware were specified in the board's Kconfig. This
patch adds the settings from Kahlee's bootblock.c to the Kconfig file
which will be needed in subsequent patches. Also add a comment about the
EM100 case.
