meta-quanta: gbs: failsafe fan speed control dynamically
1. add acpi-power-state daemon to check the ACPI power
states from BIOS
2. set failsafe fan speed at different states
- S0_G0_D0: 90%
- S5_G2: 40%
Note:
this item depends on the commit and will
add as the patches first in another PR
https://gerrit.openbmc-project.xyz/38112
3. add gbs-check-host-state.sh to monitor the power state
D-Bus and then trigger to set fan failsafe speed
4. remove gbs-detect-fan-fail service and unused scripts
from phosphor-pid-control
5. update read-margin-temp srcrev to avoid nvme temperature
sensor failed due to nvme SSD not-present
