Exynos5 series SoC does not have usb2-phy on USB3.0 Controller.
It is controlled by only usb3-phy. So, this patch remove usb2-phy
property.

Why would you want to remove the usb2-phy property ?
The usb2-phy projected here is actually the UTMI+ phy which is present
as a part of a hybrid PHY controller (that includes both UTMI+ as well
as PIPE3 phys).

And the exynos5-usbdrd phy driver also differentiates between the two PHYs.
It does try to separate out the initializations for UTMI+ and PIPE3
phy, if you notice
the functions:
exynos5_usbdrd_utmi_init() and exynos5_usbdrd_pipe3_init().

I don't think this change seems valid.
