[RFC PATCH v2 04/23] Add mcux-soc-svd subproject

[Octavian Purdila]

Add mcux-soc-svd subproject that contains SVD files that are going to
be used to generate C header with register layout definitions and
other helpers to create device models.

Guard the subproject by a configuration option since it is rarely
going to be used - whenever new headers will be generated. It is
unlikely that already generated headers will be updated, with the
exception of minor hardware revisions.

Also export the rt595 SVD file which is going to be used by subsequent
patches.

TBD: switch to a qemu gitlab fork before merge
