Squashed commit of the following:
drivers/lcd/tda19988.c: Numerous changes for a clean compilation.
drivers/lcd/tda19988: Bring in the final pieces from the FreeBSD TDA19988 driver. The driver is now code complete.
drivers/lcd/tda19988.c: Flesh on EDID read logic (still not complete). Add unlink shutdown logic.
drivers/lcd/tda19988.c: Add logic to read one EDID block.
drivers/lcd/tda19988.c: Add tda19988_read_edid() interface. Flesh read() and seek() methods.
drivers/lcd/st7032.c: Fix another error in seek method: Does not account for negative offsets!
drivers/lcd/tda19988.c: Add basic IOCTL infrastructure to support configuratin the video mode. Mostly just a framework for now.
drivers/lcd/tda19988.c: Add more register definitions. Encode page+address in the same was as FreeBSD.
drivers/lcd/tda19988.c: Add support for CEC messaging.
drivers/lcd/tda19988.c: Implement the unlink method. No IOCTLs defined yet.
drivers/lcd/tda19988.c: Add placeholders for missing character driver methods.
drivers/lcd/tda19988.c: Trivial interface improvement to permit reading multiple TDA19988 registers.
drivers/lcd/tda19988.c: Feeble start of TCA19988 drivers. Consists of lower half interface definition and some I2C helper functions. Nothing more.

1. lost data when receiving buffer is full;
2. low-water mask implement issue;
3. re-flush cdc buffer when enabling
4. serial dma is conflict with cdc , modify the serial.h
