Add support to consume phy provided by Generic phy framework.
Keeping the support for older usb-phy intact right now, in order
to prevent any functionality break in absence of relevant
device tree side change for ohci-exynos.
Once we move to new phy in the device nodes for ohci, we can
remove the support for older phys.

Changes from v5:
 - Removed setting phy explicitly to error pointer.
 - Changed error check to '-ENOSYS' instead of '-ENXIO' in failure case of
   devm_of_phy_get().

Changes from v4:
 - Removed 'phy-names' property from the bindings since we don't need it.
 - Restructured exynos_ohci_get_phy() function to handle error codes as
   well as return relevant error codes effectively.
 - Added IS_ERR() check for PHYs in exynos_ohci_phy_enable()/disable().

Changes from v3:
 - Calling usb_phy_shutdown() when exynos_ohci_phy_enable() is failing.
 - Made exynos_ohci_phy_disable() return void, since its return value
   did not serve any purpose.
 - Calling clk_disable_unprepare() in exynos_ohci_resume() when
   exynos_ohci_phy_enable() is failed.
