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.
