northdome: let ND BIC handle HOST_BOOT_TEMP's SDR (#2748)

Summary:
northdome: let ND BIC handle HOST_BOOT_TEMP's  SDR

Pull Request resolved: facebookexternal/openbmc.quanta#2748

Test Plan:
For TL case,  HOST_BOOT_TEMP sensor SDR is handled by BMC,  since TL BIC can not access the sensor.
The sensor value would send from host server via IPMI commands at TL case.
By the way, BMC do not set any threshold  value for TL's HOST_BOOT_TEMP sensor.

However, for ND case,  HOST_BOOT_TEMP could be accessed by ND's BIC,
BMC let ND's BIC to set HOST_BOOT_TEMP sensor SDR and value instead.
