Extend the Sensortag external flash Driver to support more parts

Browse Source 
The driver currently supports two Winbond external flash parts with identical instruction sets. The instruction set of the Macronix MX25R8035F appears to be a superset. We therefore change the driver to add the MID/DID of the Macronix to the list of supported parts.

This will subsequently allow us to share the same driver for both the SensorTag and the CC2650 LauchPad.
