powerpc: Fix struct termio related ioctl macros
Since termio interface is now obsolete, include/uapi/asm/ioctls.h
has some constant macros referring to "struct termio", this caused
build failure at userspace.
In file included from /usr/include/asm/ioctl.h:12,
from /usr/include/asm/ioctls.h:5,
from tst-ioctls.c:3:
tst-ioctls.c: In function 'get_TCGETA':
tst-ioctls.c:12:10: error: invalid application of 'sizeof' to incomplete type 'struct termio'
12 | return TCGETA;
| ^~~~~~
Even though termios.h provides "struct termio", trying to juggle definitions around to
make it compile could introduce regressions. So better to open code it.
