No reading or setting of lower critical and non-critical thresholds. Not initializing hysteresis. Not specifying nominal reading.

Test:

Before changes:

# ipmitool -I ipmb sensor get ddr_temp
Locating sensor record...
Sensor ID              : ddr_temp (0x9)
 Entity ID             : 7.2
 Sensor Type (Threshold)  : Temperature
 Sensor Reading        : 80 (+/- 0) degrees C
 Status                : ok
 Lower Non-Recoverable : na
 Lower Critical        : 0.000
 Lower Non-Critical    : 5.000
 Upper Non-Critical    : 95.000
 Upper Critical        : 105.000
 Upper Non-Recoverable : na
 Positive Hysteresis   : Unspecified
 Negative Hysteresis   : Unspecified
 Assertions Enabled    : lnc- lcr- unc+ ucr+
 Deassertions Enabled  : lnc- lcr- unc+ ucr+

After changes:

# ipmitool -I ipmb sensor get ddr_temp
Locating sensor record...
Sensor ID              : ddr_temp (0x9)
 Entity ID             : 7.2

@AdiFogel this is a follow-up to the dev I committed to insert the DDR temperature sensor into the SDR list. It is a tuning of the parameters meant to reflect the true capabilities of this sensor. There is no change to the functionality we need to support.
