termios: Add powerpc termios-misc

PowerPC termios.h header contains additional BSD terminal mode definitions
(sgttyb, tchars, ltchars, and associated TIOCPKT_* symbolic constants).
This patch moves all powerpc termios specific definition to its own header.

No semantic change is expected, checked on a build against a
powerpc64le-linux-gnu build.

	* sysdeps/unix/sysv/linux/powerpc/bits/termios-misc.h: New file.
	* sysdeps/unix/sysv/linux/powerpc/bits/termios.h [__USE_MISC]
	(struct sgtty, struct tchars, struct ltchars, TIOCPKT_DATA,
	TIOCPKT_FLUSHREAD, TIOCPKT_FLUSHWRITE, TIOCPKT_STOP, TIOCPKT_START,
	TIOCPKT_NOSTOP, TIOCPKT_DOSTOP, _VINTR, _VQUIT, _VERASE, _VKILL,
	_VEOF, _VMIN, _VEOL, _VTIME, _VEOL2, _VSWTC): Move to
	termios-misc.h.
	* sysdeps/unix/sysv/linux/powerpc/Makefile [$subdir == misc]
	(sysdep_headers): Add termios-misc.h.
