[devices]: Add platform support for delta ag9032v2a (#3148)

Add platform support for delta ag9032v2a
CPU: Broadwell-DE
ASIC: BMC56870 with <100Gx32 + 10Gx1>
BMC: AST2520:
- What I did
add the new platform of delta ag9032v2a
- How I did it
1.provide the QSFP and SWPLD attributes and create the virtual buses of I2C
2. provide the port configuration
- How to verify it
1. psuutil.py
2. sfputil.py
3. bcmcd

- Known issue
The port LED is not ready. We noticed that BCM chip had the M0 FW initialization issue while bringing up SDK with "BRCM SAI ver: [3.5.2.3], OCP SAI ver: [1.4], SDK ver: [6.5.14]" and here is the information :
root@sonic:/home/admin# bcmcmd "M0 status"
M0 status
0:soc_iproc_data_send_wait: No response for msg 2
M0 FW is NOT Running
M0 FW Version is 0.0
Host FW Version is 1.0
Host and M0 FW Versions do not match!!!
