glados: Support reading memory strap GPIOs to select SPD

Add some board specific code to enable the memory configuration
GPIOs in GPIO input mode and read them to determine which
memory type is on the board.

Also add the other memory types that are not yet present in
the glados mainboard directory.

This should be replaced with the real gpio infrastructure once
it is ready.
