[MIPS] Make ioremap() work on TX39/49 special unmapped segment
TX39XX and TX49XX have "reserved" segment in CKSEG3 area.
0xff000000-0xff3fffff on TX49XX and 0xff000000-0xfffeffff on TX39XX
are reserved (unmapped, uncached). Controllers on these SoCs are
placed in this segment.
This patch add plat_ioremap() and plat_iounmap() to override default
behavior and implement these hooks for TX39/TX49.
