ec/lenovo: Add guards to fix build errors without SMBIOS

Not selecting the Kconfig option `GENERATE_SMBIOS_TABLES` the build
    fails with the error below.

```
        CC         ramstage/ec/lenovo/h8/h8.o
    src/ec/lenovo/h8/h8.c:201:2: error: unknown field 'get_smbios_strings' specified in initializer
      .get_smbios_strings = h8_smbios_strings,
      ^
    src/ec/lenovo/h8/h8.c:201:2: error: initialization from incompatible pointer type [-Werror]
    src/ec/lenovo/h8/h8.c:201:2: error: (near initialization for 'h8_dev_ops.read_resources') [-Werror]
    cc1: all warnings being treated as errors
    ```

So add the appropriate preprocessor guards to fix the build error.
