README: Update "Dependencies" section.

Given that various ports now require submodules, rewrite the section
to be more generic.

Also, add git submodule update command to other sections for easy user
start.

External dependencies
---------------------
Building Unix version requires some dependencies installed. For
Building MicroPython ports may require some dependencies installed.
For Unix port, `libffi` library and `pkg-config` tool are required. On
Debian/Ubuntu/Mint derivative Linux distros, install `build-essential`
(includes toolchain and make), `libffi-dev`, and `pkg-config` packages.
Other dependencies can be built together with MicroPython. Oftentimes,

Other dependencies can be built together with MicroPython. This may
be required to enable extra features or capabilities, and in recent
versions of MicroPython, these may be enabled by default. To build
these additional dependencies, first fetch git submodules for them:
$ git submodule update --init
Use this same command to get the latest versions of dependencies, as
they are updated from time to time. After that, in `ports/unix/` dir, execute:
Use the same command to get the latest versions of dependencies, as
they are updated from time to time. After that, in the port directory
(e.g. `ports/unix/`), execute:
$ make deplibs
This will build all available dependencies (regardless whether they
are used or not). If you intend to build MicroPython with additional
options (like cross-compiling), the same set of options should be passed
to `make deplibs`. To actually enabled use of dependencies, edit
to `make deplibs`. To actually enable/disable use of dependencies, edit
`ports/unix/mpconfigport.mk` file, which has inline descriptions of the options.
For example, to build SSL module (required for `upip` tool described above),
set `MICROPY_PY_USSL` to 1.
For example, to build SSL module (required for `upip` tool described above,
and so enabled by dfeault), `MICROPY_PY_USSL` should be set to 1.
In `ports/unix/mpconfigport.mk`, you can also disable some dependencies enabled
by default, like FFI support, which requires libffi development files to
be installed.
For some ports, building required dependences is transparent, and happens
automatically. They still need to be fetched with the git submodule command
above.
