[PATCH v3 01/10] dt-bindings: phy: add exynos2200 eusb2 phy support

[Ivaylo Ivanov]

As Samsung has been using the same Synopsys eUSB2 IP in Exynos2200,
albeit with a different register layout, rename qcom,snps-eusb2-phy
to snps,eusb2-phy and drop mentions of it being only for Qualcomm SoCs
in the binding description. Document the exynos2200 eUSB2 compatible.
Unlike the currently documented Qualcomm SoCs, it doesn't provide
reset lines for reset control and uses more clocks.
