Subject: ARM: 8773/1: amba: Export amba_bustype

This patch is provided in the context of allowing the Coresight driver
subsystem to be loaded as modules.  Coresight uses amba_bus in its call
to bus_find_device() in of_coresight_get_endpoint_device() when
searching for a configurable endpoint device.  This patch allows
Coresight to reference amba_bustype when built as a module.
