linux/termios/powerpc: deal with powerpc-unique ioctl emulation
The powerpc architecture, only, emulates the termios ioctls using the
glibc termios structure. Export the real kernel ones as the termios2
interface; although the kernel doesn't call it termios2, it is exactly
the termios2 interface, and it avoids the namespace clash between the
emulated ioctls and the real kernel ioctls.
