Simple search/replace except for synclink.c where I noticed a real bug and
fixed it too.  It was doing NULL + offset, then checking for NULL if the remap
failed.

- Stop drivers calling their own flush method indirectly, it obfuscates code
  and it will change soon anyway

- A few more lock_kernel paths temporarily needed in some driver internal
  waiting code

- Remove private put_char method that does a write call for one char - we
  have that anyway

- Most but not yet all of the termios copy under lock fixing (some has other
  dependencies to follow)

- Note a few locking bugs in drivers found in the process

- Kill remaining [ab]users of TIOCG/SSOFTCAR in the driver, these must go to
  fix the termios locking

Remove all other flags for this purpose which are set almost on the same
place.  Move ports inside the board to be sure that nobody will grab reference
