nrf: Facilitate use of freeze manifest.

Browse source 
Update the Makefile to handle FROZEN_MANIFEST, and the README with some
small samples on how to use freeze manifests.  And add BOARD_DIR to the
Makefile which can be referenced in boards/<board>/mpconfigboard.mk to
include a board specific manifest.

## Compile with freeze manifest
Freeze manifests can be used by definining `FROZEN_MANIFEST` pointing to a
`manifest.py`. This can either be done by a `make` invocation or by defining
it in the specific target board's `mpconfigboard.mk`.
For example:
make BOARD=pca10040 FROZEN_MANIFEST=path/to/manifest.py
In case of using the target board's makefile, add a line similar to this:
FROZEN_MANIFEST ?= $(BOARD_DIR)/manifest.py
In these two examples, the manual `make` invocation will have precedence.
## Enable MICROPY_VFS_FAT
As the `oofatfs` module is not having header guards that can exclude the implementation compile time, this port provides a flag to enable it explicitly. The MICROPY_VFS_FAT is by default set to 0 and has to be set to 1 if `oofatfs` files should be compiled. This will be in addition of setting `MICROPY_VFS` in mpconfigport.h.
