ARM: mmp: add Trizeps6 board support

[Yupeng Schneider]

Hello Eric,

i have made a BSP for the Trizeps6 Modul based on pxa168 Processor. Here
is just a part of it, which now could be published, the other part could
not because of NDA. Now i have a question:

The Trizeps6 uses the same baseboard (ConXS) as the Trizeps4. Where would
u to place the file conxs.c to make it accessible for mach-pxa und
mach-mmp?

yours,
Y.
