ANDROID: GKI: Export two more mm symbols for GKI

Browse Source 
__get_vm_area_caller(), map_kernel_range still be needed by a vendor
for their sub-system architecture that need to be improved.
Avoid using these symbols, becuase once the vendor improves
sub-system structure they will be unexported.
