Commit 5e17b95d9893 ("phy: qcom-qmp: Utilize fully-specified DT

specify register regions for the second lane of some dual-lane PHYs.

At the time, the only two dual-lane PHYs supported by mainline were
"qcom,sdm845-qmp-usb3-phy" and "qcom,sdm845-qmp-ufs-phy" and they had
been added to the binding less than six months before the binding was
fixed.

Presumably no one is using four-year old SDM845 dtbs with mainline
anymore so drop the workaround for malformed devicetrees. In the
unlikely event that anyone complains, we can consider reverting.

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.
