Use quirks in phy individual PHY drivers to differentiate minor harware differences and drop the enum.

Stop passing it to the phy_enable call. As a reminder, dsi manager will always use DSI 0 as a clock master in a slave mode, so PLL 0 is always a clocksource for DSI 0 and it is always a clocksource for DSI 1 too unless DSI 1 is used in the standalone mode.
