wlan: set wiphy flag conditionally
In case CONFIG_ENABLE_LINUX_REG is defined, lookup NV.bin table to see
if the device is world roaming. If that is the case, set the wiphy custom
regulatory flag. Custom regulatory flag ensures the base for the channel
information set by the kernel remains as world roaming.
