targets/de10lite: use AsyncResetSynchronizer for clock domains
...
At the start output of the pll is not stabilized, which
caused malfunctions when used for sys clock domain.
Use AsyncResetSynchronizer to start clock domains
on pll locked signal.

...
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:
