soundwire: intel: fix implicit header use of module.h/export.h

These two files are implicitly relying on an instance of including
module.h from <linux/acpi.h>.

Ideally, header files under include/linux shouldn't be adding
includes of other headers, in anticipation of their consumers,
but just the headers needed for the header itself to pass
parsing with CPP.

The module.h is particularly bad in this sense, as it itself does
include a whole bunch of other headers, due to the complexity of
module support.

Here, we make those includes explicit, in order to allow a future
removal of module.h from linux/acpi.h without causing build breakage.
