commit fbcbffbac994aca1264e3c14da96ac9bfd90466e upstream.
Currently, the USB port via combophy on the RK3528/RK3588 SoC is broken.
usb usb8-port1: Cannot enable. Maybe the USB cable is bad?
This is due to the combphy of RK3528/RK3588 SoC has multiple resets, but only "phy resets" need assert and deassert, "apb resets" don't need. So change the driver to only match the phy resets, which is also what the vendor kernel does.
