Kconfig: Make the EM100 config option common 

This applied to AMD devices as well as Intel, although the mechanism is
different. Move the option to a common place.

help
The Dediprog EM100 SPI emulator allows fast loading of new SPI images
over USB. However it only supports a maximum SPI clock of 20MHz and
single data output. Enable this option to use a 20MHz SPI clock and
disable "Dual Output Fast Read" Support.
On AMD platforms this changes the SPI speed at run-time if the
mainboard code supports this. On supported Intel platforms this works
by changing the settings in the descriptor.bin file.
