...
This fixes https://github.com/enjoy-digital/litedram/issues/130 and has been tested
at 48/64/96MHz on MT41K64M16 and MT41K512M16 variants.
Also remove un-needed cd_sys2x_eb.

...
- disable DQ termination.
- disable RTT_NOM.
- drive VCCIO/GND pads.
Reduce current from 0.25A to 0.12A with: ./orangecrab.py --uart-name=usb_acm --sys-clk-freq=48e6.
Still working at 96MHz, 0.17A with: ./orangecrab.py --uart-name=usb_acm --sys-clk-freq=96e6.

targets/orangecrab.py: propagate command arguments
...
The parsed args are stripped off by soc_core_argdict() (called from
soc_sdram_argdict() so we have to pass them explicitly (or pass the
original "args", but this mimics the rest of the code in the repo).
This fixes #72

Avoid Official/Partner/Community differentiation: use same directory for all platforms/targets.
...
We initially wanted to provide different level of support for the platforms/targets, mainly
to avoid too much maintenance and let each contributor update its contributed platforms and
targets, but it's easier to update all platforms/targets all-together when LiteX evolves or
changes (and that's what has been done on litex-boards since the creation of the repository).
So let just simplify things and avoid this differentiation.
