bus: bt1-apb: Build the driver into the kernel

Seeing trigger_all_cpu_backtrace() isn't exported from the kernel and
since calling it is a very important part of driver, which may provide
a better description of a possible cause of the error, let's disable the
ability to build the driver as a loadable kernel module.
