Not beautyful ...  but as you can imagine c-tx39.c is another candidate
for eventual integration into c-r4k.c, so applied.

Thanks!

Isn't c-tx39.c too different to integrate into c-r4k.c?

TX3927(TX39H2)'s cache is almost r4k but TX3912(TX39H)'s cache is
more limited.  It does not support writeback, Hit_Invalidate_I,
Hit_Writeback_*, Index_Writeback_* operations.

And both TX39H2/TX39H do not support Create_Dirty_Excl_D so
r4k_clear_page/r4k_copy_page can not be used for any TX39XX.
