When sources of CNSS family drivers are compiled out of kernel tree, all necessary config flags will come from upper level Makefile files like wlan.mk instead of kernel defconfig. Also module symbol file will not be part of kernel build output directory anymore. Hence add changes in Android.mk to handle such case in oreder to compile WLAN host driver.
