This add an initial support for gd32 can device.
There two version of CAN ip in GD32.
Only a few early specific batches of GD32E103 can works, and CAN function have been removed for the new batch.
Because there is no eval board for GD32C103 series, I can only test it through the special GD32E103 in my hand.All commits related to GD32E103 will be marked as DNM and will be deleted when the draft is complete.
