phy: phy-rockchip-samsung-hdptx: Add support for RK3576

Despite the compatible already being listed in the bindings, the PHY
driver never gained explicit support for it. This is especially a
problem because the explicitly listed PHY addresses need to be specified
for each SoC.

To solve this, add the compatible, and a PHY config, with the address
gleaned from rk3576.dtsi.
