Add unified FRU/Elabel card with Huawei iBMC OEM IPMI support

Replaces separate IPMI FRU and SAA DMI cards with a single FRU / Elabel
card that reads all available sources in parallel and shows each field
with a color-coded source chip (IPMI FRU / Huawei iBMC / SAA DMI).

Huawei elabel fields are read/written via OEM IPMI raw commands
(NetFn 0x30, cmd 0x90) with 19-byte chunking protocol, matching
the FusionServer ElabelTool V511 wire format. Covers DeviceName,
DeviceSerialNumber, ProductName, ProductSerialNumber, ProductAssetTag,
ProductManufacturer, MainboardManufacturer, BoardProductName,
ChassisPartnumber, ChassisType (read-only), IOChassisSerial,
IOChassisAssetTag, and GUID (read-only via standard 0x06 0x08).
