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.

By default, pyocd uses generic target type called "cortex_m" which
should be able to connect and debug but not flash the memory.
Normally pyocd would warn us of using default target instead
of proper one but this message wasn't displayed.
Despite not providing target type, flashing process succeeded
but results were undefined. On Nitrogen, sometimes it worked
(especially for small images) and sometimes the programmed
device crashed miserably.
Fix flashing operation by providing pyocd target type acquired from
the conditional PYOCD_TARGET variable declared for each machine
(chip family).

Implement logic to configure what probes to program based on the
PYOCD_FLASH_IDS variable:
1. by default program all attached probes
2. change default behaviour by listing the probe IDs to flash
CONNECT_TIMEOUT_SECONDS was also renamed to maintain consistency with
the PYOCD_FLASH_IDS variable.
One can query the IDs using `pyocd list`.
The value of PYOCD_FLASH_IDS can also be injected into the datastore
using BB_ENV_EXTRAWHITE.

Currently the code flashes the firmware in a blocking way. If the host
is not configured accordingly (for example in terms of permissions),
this would hang undefinitely. This can easily confuse users and in order
to avoid this, the patch changes to unblocking session creation and
opening call, wrapping the tries in some relevant logging. The timeout
can be defined with `CONNECT_TIMEOUT_SECONDS` which defaults to 30
seconds.
Also, by default, when multiple probes are attached, the session call
will return a selection choice. This would obviously break under bitbake
with an exception:
Exception: EOFError: EOF when reading a line
Avoid this by selecting the first found probe.

Implement do_flash_usb for boards supported by pyocd:
MACHINE=xxx bitbake yyy -c flash_usb
Pyocd support abundance of boards, however for now this
meta-layer supports only one board that can be flashed
using pyocd, that is 96Boards Nitrogen.
Describe the feature in README.
