fby35: gl: Correct SDR sensor unit

[SaraLin-wiwynn]

Description

• Correct the sensor unit of SDR table. 0x00 is unsigned, 0x40 is 1's complements, and 0x80 is 2's complements.

Motivation

• BMC using sensor unit to decide method to convert threshold.

Test plan

• Build Code: Pass
• Check threshold: Pass

Log

1. Get sensor threshold.
