[platform] status led, sensors on d6254qs 6556 d7032q28b d7054q28b d7264q28b

- What I did

• Add Inventec D6254QS,D6556 platform support
• Add status led, sensors support for all inventec platform (D6254QS, D6556, D7032Q28B, D7054Q28B, D7264Q28B)
• Bug fix in transceiver_monitor.py

- How I did it

• Follow Porting Guide to port D6254QS,D6556
• Follow Porting Guide to configure sensors.conf for all inventec platform (D6254QS, D6556, D7032Q28B, D7054Q28B, D7264Q28B)
• Add drivers and python scripts for monitoring system status and doing the corresponding actions for all inventec platform ((D6254QS, D6556, D7032Q28B, D7054Q28B, D7264Q28B))
• Add one more transceiver in transceiver_monitor.py

- How to verify it

• Build image, install on device platform to make sure it is worked properly.

- Description for the changelog

• Add Inventec D6254QS,D6556 platform support
• Add status led, sensors supports for all Inventec platform (D6254QS, D6556, D7032Q28B, D7054Q28B, D7264Q28B)

build break for broadcom platform.

what are bcm56870_a0_cmh.pkg those files, zero bytes? Please remove.

why do you need these pdma settings?

thread_st = kthread_run(thread_fn, (void*)&thread_data, "inv_pthread");

what does this kernel thread do? why not move into user space?

please add license for every file. all kernel module file should be gplv2, all other files should be apache license.

#1 For build break for broadcom platform:
From console log, look like it broke becasue of kernel change from 3.16 to 4.9. We will check how to make it compiled on kernel 4.9.

#2 For lpc_ich.c
We did all these fixes before 7/E and kernel 3.6 doesn't have this module by default. We will study how to port new platform again on kernel 4.9

#3 What does this kernel thread do
use to check psu modules and fan modules and send uevent to notify user-space application for doing corresponding actions. It is better to do them in driver in case the user-space application is stopped by some unknown reason.

#4 why do you need these pdma settings?

We follows Broadcom's suggestion to configure TD3. The example bcm files are config_td3_128x25G_pwr.bcm and config_td3_tr514_os.bcm, not quite understand what they are used for from application point of view.

#5 not all attributes in this list.

Good point. Look like Broadcom doesn't announce all the attributes for TD3 yet. Without these three attributes, cancun_dir, led_fw_dir, ifp_inports_support_enable, we cannot bring up SONiC on TD3 successfully. Without the other three attributes, we got warning messages when syncd bring up.

Close this PR becaus the fixes we did was done and verified on kernel 3.6.
