    siflower: sf21 device tree fix
    
    `i2c1` node was missing `resets`, so even when enabled, the driver would
    not recognize it:
    ```
    i2c_designware c101000.i2c: Unknown Synopsys component type: 0x00000000
    ```
    
    With this fix, I2C pins on BPi-RV2 26-pin GPIO header are usable.
