Subject: [PATCH] meta-agl-jailhouse: Add support for virtio over IVSHMEM block

This patch adds the support for the virtio over IVSHMEM block for AGL with Jailhouse.

Current state of the Patchset:
- Add PCI devices from (00:0c.0 - 00:0f.0), for various virtio devices(virtio-ivshmem-{block, console, NET, custom}), primarily for virtio-blk.
- Add Common memory regions for virtio-blk in the Root-Cell and Non-Root-Linux-Cell configurations.
- Add Documentation `meta-agl-jailhouse.md` for usage and Instructions.
- Add `virtio-ivshmem-block` and `virtio-ivshmem-console` recipes for ott Kernel modules.

v2 (Anmol): Update `agl-linux-x86-demo.c` and `qemu-agl.c` for PCI macros and small descriptions for IVSHMEM PCI devices.
V3 (Anmol):
           - [RFC] Add packagegroup for the virtio-ivshmem-{block, console} applications.
           - Update the `meta-agl-jailhouse.md` for architecture specific information.
v4 (Anmol): Update recipe files according to the new syntax(3.4-honister).
v5 (Anmol):
           - Update recipe files for virtio-ivshmem binaries.
           - Update `50_local.conf.inc` for `packagegroup-agl-jailhouse`.
v5 (Anmol): Update syntax for `50_local.conf.inc`.
