Subject: [PATCH 2/2] arm64: dts: rockchip: add SATA nodes to RK3576

The Rockchip RK3576 features two SATA nodes. The first, sata0, is behind
combphy0, which muxes between pcie0 and sata0.

The second, sata1, is behind combphy1, which muxes between pcie1, sata1
and usb_drd1_dwc3.

I've only been able to test sata0 on my board, but it appears to work
just fine.
