[devices] add new accton platform minipack (#2670)

[devices] add new accton platform minipack.

Add support for new platform, minipack.
It has
CPU: Broadwell DE – D1527
MAC: Tomahawk3(BCM56980).
PHY:Broadcom BCM81724, 4 pcs, Gearbox for PIM-16Q
BMC:AST2520
8 hot-swappable Port-Interface-Modules, each of them has 16*100G QSFP.

- What I did
Add device and platform files for minipack.
- How I did it
Add as SONiC Porting Guide.
- How to verify it
decode-syseeprom
sensors
psuutil
sfputil
thermal monitor
bcmsh on port status
(port LEDs may not working)

+====================================================================
+The most of peripherals are accessed through BMC. 
+Only system eeprom and QSFP are directly accessed by CPU.
+
+System LED:
+    There are 2 system LEDs at the upper-left corner of front panel.
+
+Fan Control:
+    There are 16 fans inside 8 fan modules.
+
+Thermal sensers:
+    8 temperature sensors are controlled by the lm75 kernel modules.
+
+PSUs:
+    There r42 power supplies slot at the back.
+    Once if a PSU is not plugged, the data of it is shown all 0's.
+
+There are 128 QSFP modules are equipped. 
+Before operating on PSU and QSFP+, please make sure it is well plugged. 
+Otherwise, operation is going to fail.
