    ichsmb: add Ice Lake-LP (0x34a3) and Ice Lake-N (0x38a3) SMBus device IDs
    
    Add PCI device IDs for two Ice Lake PCH SMBus controller variants:
    - 0x34a3 (Ice Lake-LP), previously listed as the generic "Ice Lake" entry (ID_ICELAKE), renamed to ID_ICELAKELP for clarity.
    - 0x38a3 (Ice Lake-N), a separate PCH variant not previously supported.
