omap-serial: Add minimal device tree support
Adapt the driver to device tree and pass minimal platform data from device tree needed for console boot. No power management features will be suppported for now since it requires more tweaks around OCP settings to toggle forceidle/noidle/smartidle bits and handling remote wakeup and dynamic muxing.

+OMAP UART controller
+
+Required properties:
+- compatible : should be "ti,omap2-uart" for OMAP2 controllers
+- compatible : should be "ti,omap3-uart" for OMAP3 controllers
+- compatible : should be "ti,omap4-uart" for OMAP4 controllers
+- ti,hwmods : Must be "uart<n>", n being the instance number (1-based)
+
+Optional properties:
+- clock-frequency : frequency of the clock input to the UART
