tools: termios_linux.h: Fix build error on ppc64

Browse Source 
Commit 93b55636b0 ("tools: kwboot: Allow any baudrate on Linux") added a
tcgetattr() function to be used, instead of the libc's termios functions.

This was done to allow using the raw TCGETS2/TCSETS2 ioctls that allow to
support arbitrary baud rates.

This breaks the build for PowerPC, because that architecture does not have
a struct termios2 defined because the termios and ktermios are the same.

On PowerPC, the termios ioctl() emulates the TCGETS2/TCSETS*2 ioctls with
tcgetattr/tcsetattr using just the struct termios (that's as mentioned the
same than what is defined as struct termios2 in other architectures).

So there is no need to use the TCGETS2/TCSETS2 ioctls on that architecture
and just TCGETS/TCSETS ioctls with termios as defined by PowerPC is enough.
