Add support for Synopsys DWC3 core, with only BULK endpoints supported at the moment, as well as a few Lattice-specific quirks hardcoded, who use a core with a compatible API in one of its FPGA. Signed-off-by: Josuah Demangeon <[email protected]>

Dependencies:
A very similar core is implemented on a Lattice FPGA, for which everyone is able to build its own SoC for.
One example of SoC for this core is in a separate SDK whose content is not yet ready to be upstreamed (upcoming changes planned): https://github.com/tinyvision-ai-inc/tinyvision_zephyr_sdk
I still need to implement the "quirks" properly, taking the DWC2 as a template. So this is still a draft. However, comments are still welcome!
