ti-dmai: Allow do_prepsources to run release.sh

The do_prepsources task runs after do_unpack at which point the
${S}/patches directory has been created.  In the last step of
do_prepsources, code should be copied over to ${S} by the release.sh
script.  However, this script silently fails if the target directory
(${S}) is not empty---it contains the 'patches' directory.  The
failure manifests in the do_patch step when trying to applying patches
against the source which wasn't populated by release.sh.

Here, we pre-emptively clean out the directory release.sh intends to
use.  The patch directory is re-created by the do_patch step.
