Change the phy provider used from the old usb phy specific to a new one using the generic phy framework.
Signed-off-by: Jingoo Han <jg1....@samsung.com> Cc: Kamil Debski <k.deb...@samsung.com> --- Exynos OHCI driver also uses Exynos USB2.0 PHY. Thus, I make this patch based-on Kamil Debski's patchset for adding Exynos USB 2.0 PHY driver.
