mainboard: Add Synology DS918+

I'm new to coreboot.
This port is based on 4.13, this board boots. Tested with tianocore.
Can provide serial logs, original Synology's DSM OS works fine with this
port. Can run tests on my board.
Now works on Master.
Things todo:
* polish
* I211 ethernet chips don't work in OS
* 2nd HSUART Serial doesn't work in OS, only in original DSM. Tried all
  console=ttyS*,115200 and all 'set tty com*' (as per obsd), probably
  not cb problem.
* Freebsd usb stick causes X86 exception, OpenBSD fails to boot at
  entry point 0x1001000. Both have apl support. log:

* ...
