Add the OMAP5 HDMI core IP library. This will used by the hdmi5 driver to configure the HDMI core sub block found on OMAP5/DRA7x. The new HDMI core IP consists of the video composing sub blocks: video sampler, color space converter, video packetizer and frame composer. These are connected to each other serially. There is an i2c/ddc master sub block which is responsible for reading EDID info. Each of the video sub block is programmed in hdmi5_configure. Currenlty, only the minimal features for each sub block are exposed. We can configure the core only in 24 bit color mode. As we add more features, the register programming to configure the serial sub blocks will increase in complexity. The register configurations for enabling and clearing interrupts are provided, but interrupts themselves aren't used at the moment. One place where they will come in use to read the hdmi ddc block's register which recieves a byte of data from the slave. We currently just read the register after every millisecond.
