Remove termios2 ioctl defintions from public headers

The use of the termios2 ioctl interface is an implementation detail which
should not bleed into public headers.  Remove the PowerPC version of
<bits/ioctls.h> and define the termios2 ioctl numbers in <termios_arch.h>
instead.  Also remove the include check from there which is unneeded in an
internal header.
