mb/amd/majolica/Kconfig: add EFS SPI settings

This keeps the default of EFS_SPI_SPEED at 66.66Mhz for the non-EM100
case, but switches the EFS_SPI_READ_MODE setting from Dual IO (1-1-2) to
Quad IO (1-1-4) for the non-EM100 case. This patch adds a special config
for the EM100 emulator case that has limited SPI frequency support.

Tested on Majolica by Martin.
