Tested-by: Nicolas Frattaroli <frattaroli.nicolas@gmail.com>

Applied this on top of 5.16-rc4, added the necessary device tree
changes to rk356x.dtsi and rk3566-quartz64-a.dts and ran it on
my Quartz64. I tested PCIe2x1 on the one combphy and SATA on the
other, simultaneously. Devices were detected correctly (with some
hiccups on SATA due to a Quartz64 Model A design issue, but it
was detected eventually) and some transfers were done to ensure
it's stable. It is stable.

Nicolas Frattaroli
