recipes-kernel: update driver recipes
This patch changes the recipes to fetch the driver sources from AGL's src directory. It therefore removes the redundant source files from the recipe directory. Change-Id: Ib3c48a0c7e79144713ccd8e10a89185cd929b41c Signed-off-by: Christian Gromm <christian.gromm@microchip.com> (cherry picked from commit 1ea0cef6934ccadc36395b60d8b8d58d69016e28)
