phy: rockchip-snps-pcie3: only look for rockchip,pipe-grf on rk3588
The rockchip,pipe-grf property is only used on rk3588, but not on
rk3568. Therefore this property is not present on rk3568 devices,
leading to the following message:

phy: ti: gmii-sel: Add support for CPSW5G GMII SEL in J7200
Each of the CPSW5G ports in J7200 support additional modes like QSGMII.
Add a new compatible for J7200 to support the additional modes.
In TI's J7200, each of the CPSW5G ethernet interfaces can act as a
QSGMII or QSGMII-SUB port. The QSGMII interface is responsible for
performing auto-negotiation between the MAC and the PHY while the rest of
the interfaces are designated as QSGMII-SUB interfaces, indicating that
they will not be taking part in the auto-negotiation process.
To indicate the interface which will serve as the main QSGMII interface,
add a property "ti,qsgmii-main-ports", whose value indicates the
port number of the interface which shall serve as the main QSGMII
interface. The rest of the interfaces are then assigned QSGMII-SUB mode by
default. The property "ti,qsgmii-main-ports" is used to configure the
CTRLMMR_ENETx_CTRL register.
Depending on the device, it is possible for more than one QSGMII main port
to exist. Thus, the property "ti,qsgmii-main-ports" is defined as an array
of values in order to reuse the property for other devices.
