Resolution of Issue 619 will require multiple steps, this part of the first step in that resolution: Every call to nxsem_wait_uninterruptible() must handle the return value from nxsem_wait_uninterruptible properly. This commit is only for those files under drivers/audio, drivers/net, and drivers/lcd.
* Simplify EINTR/ECANCEL error handling
1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx
* Unify the void cast usage
1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro

drivers/lcd/ft80x: ACTIVE host command appears to be formatted differently than other host commands; Fix ROM CHIPID. Appears to be big-ending, BCD.
drivers/lcd/ft80x: Fix some compile issues when debug features are enabled.
drivers/lcd and include/nuttx/lcd: Add FT80x support for writing to graphics memory. Also add some definitions needed by apps/examples/ft80x for bitmap manipulation.
drivers/lcd: Review/update FT80x initializatin logic
drivers/lcd: Rename ft80x_base.c to just ft80x.c. Add logic to notify FT80X clients of events via signals.
drivers/lcd: Trivial updates to naming. Add some new definitions.
