[MIPS] IP32 Fix and complete IP32 parport definitions
Fix, complete, and indent IP32 parport definitions. Definition were wrong for CTXINUSE and DMACTIVE (1-bit shift). Add macros DATA_BOUND, DATALEN_SHIFT, and CTRSHIFT. Signed-off-by: Arnaud Giersch <arnaud.giersch@free.fr> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
