soundwire: Update the includes on the sdw.h header

There are quite a few things used in the sdw.h header that it relies on
the consumer to include. If something is used directly in the header it
should be included by the header. Update the includes to cover the
missing items, or add forward declarations for things that are only used
as pointers. Whilst making the change also alphabetise the list of
includes.
