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.
