Summary:

This PR introduces support for the Minipack3BAM platform by porting and adapting configurations from the existing Minipack3BA platform. Key updates include the integration of NETLAKE-2 I2C device mappings and necessary kernel configuration adjustments.

Kernel Configuration:

• Enabled CONFIG_SENSORS_INA2XX and CONFIG_SENSORS_SPD5118 for power and memory monitoring.

Platform Manager:

• Standardized CPU bus naming using the virtual bus "CPU_BUS".
• Implemented versionedPmUnitConfigs for NETLAKE-2 hardware identification.
• Updated pmUnitConfig, symbolicLinkToDevicePath, and CPU_CORE_TEMP sysfs paths to align with NETLAKE-2 I2C topology.

Sensor Service:

• Migrated "NETLAKE" sensor definitions and sysfs paths to support the new hardware layout.

Firmware Utility:

• Updated fw_util BIOS upgrade logic to support NETLAKE-2 specific flash sequences.

No Changes Required:

bsp_tests.json, fan_service.json, led_manager.json.

Test Plan:

Platform Manager:

• Executed platform_manager and platform_manager_hw_test on Minipack3BAM; all functional logs validated and tests passed.

Sensor Service:

• Verified initialization of universal and versioned sensors via sensor_service, sensor_service_hw_test, and sensor_service_client.
