arm: omap3: Make try_unlock_memory() static

try_unlock_memory() is only used in one file, so make it static
in that file,remove it from the sys_proto header file, and relocate
it into the #ifdef section that call it. This will make it only built
under the conditions when it is called, and it may help with some
further optimization in the future.
