This patch cleans up handling of reference clock rate in Samsung USB PHY
drivers. It is mostly a cosmetic change but improves error handling in
case of failing to get reference clock or invalid clock rate.

Moving register and structure definitions to header file,
and keeping the generic functions to be used across
multiple PHYs in common phy helper driver under SAMSUNG_USBPHY,
and moving USB 2.0 PHY driver under SAMSUNG_USB2PHY.
Also allowing samsung PHY drivers be built as modules.
