meta-zephyr-core/bsp: Restructure into sublayers

This commit restructures meta-zephyr into meta-zephyr-core and
meta-zephyr-bsp. It moves machine definitions into meta-zephyr-bsp
in preparation for adding the autogenerated zephyr machines.

+Building Zephyr Images via bitbake recipes
+==========================================
+
+More detailed and up-to-date information can be found here:
+
+https://wiki.yoctoproject.org/wiki/TipsAndTricks/BuildingZephyrImages
+
+Prerequisites:
+==============
+
+This layer depends on:
+    Yocto distro (master)
+        git://git.yoctoproject.org/poky
+    Python layer (meta-openembedded/meta-python)
+        git://git.openembedded.org/meta-openembedded
+
+Modify local conf by adding:
+    DISTRO="zephyr"
+
+Add "meta-openembedded/meta-oe" to BBLAYERS
+Add "meta-openembedded/meta-python" to BBLAYERS
+Add "meta-zephyr" to BBLAYERS
+
+Building and Running Zephyr Samples
+===================================
+
+You can build Zephyr samples. There are several sample recipes.
+For example, to build the Zephyr "philosophers" sample:
+    
+    $ MACHINE=qemu-x86 bitbake zephyr-philosophers
+    
+You can then run the created "philosophers" image in qemu:
+
+    $ runqemu qemu-x86
+    
+The same sample, for ARM image:
+
+    $ MACHINE=qemu-cortex-m3 bitbake zephyr-philosophers
+    $ runqemu qemu-cortex-m3
+    
+The same sample, for Nios2 image:
+
+    $ MACHINE=qemu-nios2 bitbake zephyr-philosophers
+    $ runqemu qemu-nios2
+
+Flashing
+=================================
+
+You can flash Zephyr samples to boards. Currently, the following MACHINEs
+are supported:
+ * DFU:
+  - arduino-101-sss
+  - arduino-101
+  - arduino-101-ble
+ * pyocd:
+  - 96b-nitrogen
+
+To flash the example you built with command e.g.
+
+    $ MACHINE=96b-nitrogen bitbake zephyr-philosophers
+
+call similar command with explicit flash_usb command:
+
+    $ MACHINE=96b-nitrogen bitbake zephyr-philosophers -c flash_usb
+
+dfu-util and/or pyocd need to be installed in your system. If you observe
+permission errors or the flashing process seem to hang, follow those instructions:
+https://github.com/pyocd/pyOCD/tree/master/udev
+
+By default, pyocd tries to flash all the attached probes. This behaviour can be
+customised by defining the PYOCD_FLASH_IDS variable as a space-separated list
+of IDs. Once that is set, the tool will only try to program these IDs. You can
+query for the IDs by running `pyocd list` on your host while having the probes
+attached. Besides setting this variable through the build's configuration or
+metadata, you can also inject its value from command line with something like:
+
+    $ PYOCD_FLASH_IDS='<ID1> <ID2> <ID3>' BB_ENV_EXTRAWHITE="$BB_ENV_EXTRAWHITE PYOCD_FLASH_IDS" bitbake <TARGET> -c flash_usb
+
+Building and Running Zephyr Tests
+=================================
+Presently only toolchains for ARM, x86, IAMCU and Nios2 are supported.
+(For ARM we use CortexM3 toolchain)
+
+To run Zephyr Test using Yocto Image Tests, ensure following in local.conf:
+
+    INHERIT += "testimage"
+
+You can build and test an individual existing Zephyr test.
+This is done by appending the actual test name to the "zephyr-kernel-test",
+for example:
+
+    $ MACHINE=qemu-x86 bitbake zephyr-kernel-test-sleep
+    $ MACHINE=qemu-x86 bitbake zephyr-kernel-test-sleep -c testimage
+
+You can also build and run all Zephyr existing tests (as listed in the file
+zephyr-kernel-test.inc). For example:
+
+    $ MACHINE=qemu-x86 bitbake zephyr-kernel-test-all
+    $ MACHINE=qemu-x86 bitbake zephyr-kernel-test-all -c testimage
+or 
+    $ MACHINE=qemu-cortex-m3 bitbake zephyr-kernel-test-all
+    $ MACHINE=qemu-cortex-m3 bitbake zephyr-kernel-test-all -c testimage
+or 
+    $ MACHINE=qemu-nios2 bitbake zephyr-kernel-test-all
+    $ MACHINE=qemu-nios2 bitbake zephyr-kernel-test-all -c testimage
+
