Prepare master for new framework integration

During the last workshop the transition to the new framework was presented.
This change essentially deprecates the SMACK-based application framework.

To prepare the integration of it, we remove the deprecated components:
- recipes-apis : all agl-service-*
- recipes-demos: all demo apps but homescreen
- non-essential configurations

Todo:
We need to bring-back the html5 image in a follow-up w/o ties into the old framework.

v2: kept WAM + Chromium recipes for reference
v3: rebased

Bug-AGL: SPEC-4121

-Subject: [PATCH 2/2] src: most: add auto conf feature
-
-This patch adds the auto configuration feature to the driver
-sources. It is needed to have the driver configured automatically
-upon start up w/o the need for userspace to set up sysfs.

-Subject: [PATCH] staging: most: dim2: use device tree
-
-Current dim2 driver expects the existence of a platform driver that
-implements the platform specific initialization and delivery of the irq
-numbers.
-
-This patch integrates the device tree activity and platform specific
-code into the driver.

-Subject: [PATCH] staging: most: dim2: use device for coherent memory allocation
-
-On several modern architectures the allocation of coherent memory needs
-a device that has the dma_ops properly set.  This patch enables use of
-the DIM2 platform device for the allocation process.
