rockchip: nanopi r5s: fix gmac reset gpios

Browse Source 
Move reset gpios to gmac node otherwise the dwmac driver will fail to
lookup ethernet phy:

> [   10.398514] rk_gmac-dwmac fe2a0000.ethernet eth0: no phy found
> [   10.399061] rk_gmac-dwmac fe2a0000.ethernet eth0: __stmmac_open: Cannot attach to PHY (error: -19)
