Sync Darwin and Darwin48V configs

[aalamsi22]

Description

• Updates the PM configs for darwin & darwin48v to initialize the qsfp ports (1-32) and generate the necessary symlinks.
• Fix misconfigured infoRomConfigs to use the correct register offset of 0x100.
• Sync Darwin sensor_service config to include all sensors.
• Sync Darwin led_manager paths to follow the same /sys/class/leds used on other platforms. Also adds missing rackmon fan as a fru associated with the FAN led.

NOTE: The SFP ports on 33 & 34 aren't initialized as driver lacks support

Additionally, this fixes a recent escalated issue where the sensorPOS_3V3_ALW was throwing critical alarms due to a missing configuration with how the sensor value is computed.

Testing

Ports on Darwin48V reflect the expected values through the scd-xcvr driver

Port 1 is expected to be present

# cat /run/devmap/xcvrs/xcvr_ctrl_1/xcvr1_present
0 <-- 0 is present

Testing with a non-existing xcvr

# cat /run/devmap/xcvrs/xcvr_ctrl_5/xcvr5_present
1  <---- 1 is absent
