tao zeng 97bd5986ae mm: add cma debug interafce [1/1] 
PD#GH-17

Problem:
sometimes cma allocation failed but it's hard to get
failed log and need recompile code.

Solution:
Add /proc/cma_debug to open cma debug message dynamic.
By default, no debug message is printed. If you write a
value large than 0 to this node, debug message will be
printed.

Verify:
