src: Remove redundant use of ACPI offset(0)

IASL version 20180927 and greater, detects Unnecessary/redundant uses of
the Offset() operator within a Field Unit list.
It then sends a remark "^ Unnecessary/redundant use of Offset"

example:
    OperationRegion (OPR1, SystemMemory, 0x100, 0x100)
    Field (OPR1)
    {
        Offset (0),     // Never needed
        FLD1, 32,
        Offset (4),     // Redundant, offset is already 4 (bytes)
        FLD2, 8,
        Offset (64),    // OK use of Offset.
        FLD3, 16,
    }

We will have those remarks:
dsdt.asl     14:         Offset (0),
Remark   2158 -                 ^ Unnecessary/redundant use of Offset operator

dsdt.asl     16:         Offset (4),
Remark   2158 -                 ^ Unnecessary/redundant use of Offset operator
