[202012] [Mellanox] Read transceiver EEPROM via sdk sysfs (#12399) 
- Why I did it
ethtool is not able to read certain pages(eg. page 11h) of CMIS cables.
SDK provides a set of sysfs to expose the transceiver EEPROM, now we migrate from using ethtool to read these sysfs for transceiver EEPROM reading.

- How I did it
replace ethtool with accessing the SDK sysfs for cable EEPROM reading.
Adjust the offset according to the SDK sysfs memory map.

- How to verify it
run sonic-mgmt sfp-related regression test case.

# identifier value of xSFP module which is in the first byte of the EEPROM
# if the identifier value falls into SFP_TYPE_CODE_LIST the module is treated as a SFP module and parsed according to 8472
# for QSFP_TYPE_CODE_LIST the module is treated as a QSFP module and parsed according to 8436/8636
# Originally the type (SFP/QSFP) of each module is determined according to the SKU dictionary
# where the type of each FP port is defined. The content of EEPROM is parsed according to its type.
# However, sometimes the SFP module can be fit in an adapter and then pluged into a QSFP port.
# In this case the EEPROM content is in format of SFP but parsed as QSFP, causing failure.
# To resolve that issue the type field of the xSFP module is also fetched so that we can know exectly what type the
# module is. Currently only the following types are recognized as SFP/QSFP module.
# Meanwhile, if the a module's identifier value can't be recognized, it will be parsed according to the SKU dictionary.
# This is because in the future it's possible that some new identifier value which is not regonized but backward compatible
# with the current format and by doing so it can be parsed as much as possible.

for QSFP, originally I would like to make use of Initialization complete flag bit
which is at Page a0 offset 6 bit 0 to test whether reset is complete.
However as unit testing was carried out I find this approach may fail because:
1. we make use of ethtool to read data on I2C bus rather than to read directly
2. ethtool is unable to access I2C during QSFP module being reset
In other words, whenever the flag is able to be retrived, the value is always be 1
As a result, it doesn't make sense to retrieve that flag. Just treat successfully
retrieving data as "data ready".
for SFP it seems that there is not flag indicating whether reset succeed. However,
we can also do it in the way for QSFP.
