[Mellanox] Enhance Platform API to support SN2201 - RJ45 ports and new components mgmt. (#10377)

Browse Source 
* Support new platform SN2201 and RJ45 port

Signed-off-by: Kebo Liu <kebol@nvidia.com>

* remove unused import and redundant function

Signed-off-by: Kebo Liu <kebol@nvidia.com>

* fix error introduced by rebase

Signed-off-by: Kebo Liu <kebol@nvidia.com>

* Revert the special handling of RJ45 ports (#56)

* Revert the special handling of RJ45 ports

sfp.py
sfp_event.py
chassis.py

Signed-off-by: Stephen Sun <stephens@nvidia.com>

* Remove deadcode

Signed-off-by: Stephen Sun <stephens@nvidia.com>

* Support CPLD update for SN2201

A new class is introduced, deriving from ComponentCPLD and overloading _install_firmware
Change _install_firmware from private (starting with __) to protected, making it overloadable

Signed-off-by: Stephen Sun <stephens@nvidia.com>

* Initialize component BIOS/CPLD

Signed-off-by: Stephen Sun <stephens@nvidia.com>

* Remove swb_amb which doesn't on DVT board any more

Signed-off-by: Stephen Sun <stephens@nvidia.com>

* Remove the unexisted sensor - switch board ambient - from platform.json

Signed-off-by: Stephen Sun <stephens@nvidia.com>

* Do not report error on receiving unknown status on RJ45 ports

Translate it to disconnect for RJ45 ports
Report error for xSFP ports

Signed-off-by: Stephen Sun <stephens@nvidia.com>

* Add reinit for RJ45 to avoid exception

Signed-off-by: Stephen Sun <stephens@nvidia.com>

Retrieves the reset status of SFP
Returns:
A Boolean, True if reset enabled, False if disabled
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.
