amd/southbridge: Change #if defined to #if IS_ENABLED

The IMC functions were being called and timing out when the
    CONFIG_SB800_IMC_FWM/CONFIG_HUDSON_IMC_FWM were defined as 0.
    Changing to a IS_ENABLED will keep the IMC handshake from
    occuring if the IMC firmware isn't running.

Tested on a Persimmon platform which makes three calls to
    spi_claim_bus() with each call timing out after 500ms.
