Add the change to build and set WLAN driver as default for different targets based on target specific flags WIFI_DRIVER_BUILT and WIFI_DRIVER_DEFAULT. KERNEL_TO_BUILD_ROOT_OFFSET needs to be set a default value if upper level makefiles do not define it. Change-Id: I4768b8c75a5d4042d01c3ddfb67b20c13e42463a CRs-fixed: 1005069
