devicetree: fix newly added exynos sata bindings
Commit ba0d7ed391b7b "ARM: dts: enable ahci sata and sata phy for exynos5250" added a new binding document for the sata phy device, and changed the sata controller binding. However, in both cases significant aspects of the binding remained undocumented. This attempts to reconstruct the actual binding from the usage.
