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.

phy: rockchip-inno-usb2: Return zero after otg sync

The otg sync state patch reuses the ret variable, but fails to set it to
zero after use. This leads to a situation when the otg port is in
peripheral mode where the otg phy aborts halfway through setup.  It also
fails to account for a failure to register the extcon notifier. Fix this
by using our own variable and skipping otg sync in case of failure.

Add data-lanes property for splitting pcie-lanes across controllers.

The data-lanes is an array where x=0 means lane is disabled and  x > 0
means controller x is assigned to phy lane.
