Differentiate flash part across sensortag/cc2650 versions

Browse Source 
Older CC2650 sensortags have a Winbond W25X40CL 4MBit SPI flash. Newer ones have a Macronix MX25R8035F 8MBit part. The parts have almost identical instruction sets and are both supported by our generic external flash driver. The key difference between the two parts is that they have different Manufacturer and Device IDs.

This commit allows us to switch between the two: We default to the new revision, and allow users to build for the older one by defining `SENSORTAG_CC2650_REV_1_2_0` to 1.

Current tags are version 1.5.1. Older tags are version 1.2.0. To identify older tags, look for "Rev: 1.2" printed on the PCB. They should also have a sticker that reads "Rev: 1.3.0" and "HW Rev 1.2.0".
