Subject: [PATCH v3 3/3] arm64: dts: rockchip: k3566-quartz64-a: adds sata
 variant

The Quartz64 board is built upon Rockchip RK3566.
Rockchip RK3566 has two combo phys.
The first connects USB3 and SATA ctrl1, and the second PCIe lane and SATA
ctrl2.
The second combo phy is hardwired to the PCIe slot, where for the first,
the hardware on the board provides both the USB3 connector and the SATA
connector.
This DT allows the users to switch the combo phy to the SATA connector.
