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.

Add the Hackaday Supercon 2019 badge which has an ECP5 FPGA:
https://hackaday.io/project/167255-2019-hackaday-superconference-badge
These changes are from Michael Welling's fork:
https://github.com/mwelling/linux-on-litex-vexriscv
During Supercon, we trying two approaches:
- use the built-in 16MB QSPI SRAM
- use add-on cartiridge with 32MB SDRAM by Jacob Creedon
We were not able to get the QSPI SRAM working so I've removed
those changes, and I have just added the changes that are needed
to boot Linux with the 32MB SDRAM.
Thanks to Jacob Creedon, Greg Davill and Tim Ansell who helped debug.
KiCad design files for the SDRAM cartridge are available at:
https://github.com/jcreedon/dram-cart/
The SDRAM cartridge PCB is shared at:
