[device/celestica]: libsensors configuration file for Seastone-DX010

[mudsut4ke]

- What I did

• Update sensor configuration file follow thermal specification document

- How I did it

1. Update lm75b sensor threshold

- How to verify it

• Run command sensors under sonic and check lm75b sensor threshold

@yxieca , this PR refer to sensor alarm issue on Seastone-DX010

@mudsut4ke While your change might be addressing other issues. It didn't address the test failure fully. Looks like the ASIC max_hyst is default set to 28 and the temperature reading is 37, which is higher than the max_hyst. Can you propose another change and test it before posting it?

        }

Didn't fully address the observed test failure.

@yxieca , temp1_max_hyst was set to 28 because of old sensor config,
Anyway I have added 5 °C hysteresis temperature follow default value in lm75 datasheet to avoid the issue.
