meta-agl-demo: recipes-kernel: update MOST driver recipes

This patch updates the recipes used to build the MOST driver.
Since the driver source directory holds version 1.4.0-stable
as of commit f19c18408b515c5e33f96893cbe213d9ab30b904 it also
adds backport patches for the MOST sound and networking driver
needed to build for porter.

v2 (jsmoeller): combine with c8359
