Enable Wireplumber Policy instance in ivi guest image.

-add wireplumber-policy-config-agl recipe to guest, while wireplumber-config-agl remains in host. -add packagegroup-pipewire-base which is needed by the policy recipe. -mount host pipewire server socket in /var directory in guest image and define a PIPEWIRE_RUNTIME_DIR environment variable based on this new mount point. -make the needed service file changes to have wireplumber policy instance start on its own with out depending on pipewire service, limit this change to lxc layers. -install wireplumber@policy.service in sockets.targets.want directory, this is need for its self start, limit this change to lxc layers Bug-AGL: SPEC-4100 Signed-off-by: Ashok Sidipotu <ashok.sidipotu@collabora.com> Change-Id: Ifbd7a026c75a199bb540c1593d5a93f67a4bde02

From 8e16207392cd715ea88f6780981a3d55ab005588 Mon Sep 17 00:00:00 2001 From: Andrey Shvetsov <andrey.shvetsov@k2l.de> Date: Mon, 12 Feb 2018 12:23:37 +0100 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.
