Samsung DTS ARM64 changes for v6.7

1. Exynos850: Add support for USB 2.0 (host and device) and enable it on
    E850-96 board.
 
 2. Exynos5433: Switch sound card to generic audio-routing property,
    supported since previous release for Samsung drivers.  The old
    samsung,audio-routing property is deprecated.
 
 3. Few cleanups.
