tty: let architectures override the user/kernel macros.
Give architectures that support the new termios2 the possibilty to overide the user_termios_to_kernel_termios and kernel_termios_to_user_termios macros. As soon as all architectures that use the generic variant have been converted the ifdefs can go away again. Architectures in question are avr32, frv, powerpc and s390.
