[OpenBMC] Update PowerSupplyRedundancy to use the correct endpoints

[whowutwut]

Talking to the Firmware team today, the implementation of Power Supply is using the old interface and the correct way to get/set the value is using the setValue and getValue endpoints:

I think the PS sensor, even though the object is in the xyz/ namespace, implements the old PS interface. The right way to set a value is by calling 'SetValue' or something equivalent.

Those are these commands:

curl -b cjar -k -H "Content-Type: application/json" -X POST \
https://$BMC_IP/xyz/openbmc_project/sensors/chassis/PowerSupplyRedundancy/action/getValue \
-d '{"data": []}'

curl -b cjar -k -H "Content-Type: application/json" -X POST \
https://$BMC_IP/xyz/openbmc_project/sensors/chassis/PowerSupplyRedundancy/action/setValue \
-d '{"data": ["Enabled"]}'

curl -b cjar -k -H "Content-Type: application/json" -X POST \
https://$BMC_IP/xyz/openbmc_project/sensors/chassis/PowerSupplyRedundancy/action/setValue \
-d '{"data": ["Disabled"]}'

Update the xCAT code to use these correct endpoints

Verified, so close this issue.
