[PATCH V2 0/2]Add mxc 3ds CPLD debugboard support

[Jason Wang]

part2(v2):

Diff VS v1:
1) change file name from cpld_debugboard to 3ds_debugboard.
2) move all macro definitions from 3ds_debugboard.h to 3ds_debugboard.c
3) add a wrapper function in the 3ds_debugboard.c for lan9127 init.

I have validated build test for mx31_3ds for v2, and performed boot test
for V1 on mx31_3ds(NFS worked fine).
