    rockchip: fix phy reset on rk356x
    
    The commit 7160820d742a ("phy: rockchip: naneng-combphy: fix phy reset")
    was backported to kernel 6.6 branch by upstream, however the correspond
    dtsi fixes was not, resulting the following error:
    ```
    [    0.225521] rockchip-naneng-combphy fe830000.phy: error -ENOENT: failed to get phy reset
    [    0.227467] rockchip-naneng-combphy fe840000.phy: error -ENOENT: failed to get phy reset
    ```
    
    So backport the dtsi fixes here manually.
