This commit provides a **bug fix** for the **`weutil` utility** on the **ICECUBE800BANW platform**, addressing an incorrect offset for the **SMB EEPROM**. Previously, a new SMB EEPROM target was introduced, but its offset was not correctly applied as zero, leading to issues in reading its data. The change in `fboss/platform/weutil/ConfigUtils.cpp` now explicitly sets the SMB EEPROM offset to 0 within the `getFruEepromList` function, bypassing the problematic dynamic retrieval. This ensures accurate access and validation of the **SMB EEPROM** contents, resolving the data access problem.

This commit introduces **temporary special handling** for the **SMB EEPROM** on the **ICECUBE800BANW** platform, specifically when it resides on the CPU bus. It modifies `fboss/platform/platform_manager/PlatformExplorer.cpp` to correctly identify and generate human-readable content for this EEPROM, and updates `fboss/platform/weutil/ConfigUtils.cpp` to include it in the FRU EEPROM list. This **new capability** is a **workaround** to address the current architectural assumption that an SCM EEPROM target always exists. The changes ensure that `platform manager` and `weutil` can properly interact with the SMB EEPROM for the **ICECUBE800BANW** platform, enabling correct hardware information retrieval.
