HDMI wrapper is a block common to DSS in OMAP4, OMAP5 and DRA7x. Move the existing functions from ti_hdmi_4xxx_ip.c to a separate file. These funcs are called directly from the hdmi driver rather than hdmi_ip_ops funtion pointer calls. Add new wrapper funcs which can be used by other hdmi libraries like core, pll and phy. Move some of the enums, structs and funcs related to the wrapper from ti_hdmi_4xxx_ip.h to ti_hdmi.h. These will be shared amongst the omap4/5 hdmi platform drivers and other libraries. The old hdmi_wp_init() is removed since it didn't do anything. Timing parameters like interlace, hsync_level and vsync_level weren't copied correctly before. Those are copied correctly now.
