[202111][Mellanox] Update hw-mgmt package to version V.7.0020.2004 (s…

…onic-net#10402)

This PR is to backport sonic-net#10401 to 202111

- Why I did it
Take new hw-mgmt release to SONiC, including:
new features:

hw-mgmt: add to PSU FW upgrade tool command to show current FW version
hw-mgmt: add to PSU FW upgrade tool support for single-PSU-in-the-system FW upgrade
hw-mgmt: add attribute “/firmware” to show FW version of restricted upgradable PSUs only
hw-mgmt: Add NVME temperature reports attributes (_alarm/_crit/_min/_max)
bug fix:

psu: redundant i2c_addr attributes being created for psu 3 & 4 in system having only 2 psus.
hw-mgmt: in SPC1/2 i2c driver removal is too slow vs. ASIC reset causing non-functional log errors
PSU thresholds sysfs changed in 5.10 to “read only” preventing modification (modification required due PSU HW bug)
CPLD3 sysfs attribute missing after chip down/up flow
sysfs attributes missing when hw-mgmt is restarted (stop/start) within systemd
release notes can be found from link https://github.com/Mellanox/hw-mgmt/blob/V.7.0020.2004/debian/Release.txt

- How I did it
Update hw-mgmt make file with new version number
Update hw-mgmt submodule pointer

- How to verify it
Run platform regression on all Mellanox platform
