Roy Lee b45c1aca73 [device] Adding platform support for Accton as7315-27xb (#3301)
This switch has 27 fiber ports, 4x25G, 20x10G , and 3x100G ports ports.
CPU: Intel ® Atom™ Processor C3508,1.6GHz
BMC: None
MAC: Broadcom BCM88470 (Qumran AX).
MISC: Support IEEE1588v2, hot-swappable PSU, hot-swappable fan tray.

But notice here, BCM88470 is not supported for SAI now.
So the syncd container is not running so far.
