Subject: [PATCH 4/8] phy: exynos5-usbdrd: Make it possible to pass custom phy ops

Provide a way to use different PHY ops for different chips. Right now
all chips are using exynos5_usbdrd_phy_ops, but it won't always be the
case. For example, Exynos850 has very different USB PHY block, so there
will be another PHY ops implementation for that chip.

No functional change.
