CC2640:Change RF front end mode and bias

1. In ../main.c define your own BLE configuration template.
2.The option and default configuration is define in ../ble_user_config.h
 

The internal bias and external bias is determine by the RX_TX pin, which didn't implement in 7x7 package.In our application we use the CC2592 as PA and use 5x5 package for smaller footprint, and the configuration is differential mode internal bias.
