[nRF52] compile error in ble_drv.c with fix

[FoldedToad]

I am building micro python with on a Ubuntu 16.04 system using the Ubuntu gcc toolchain package (see gcc info below) --

robin@deeplearner:~/micropython/ports/nrf$ gcc --version

I have a patch file which fixes this problem but I can't attach it (yet), so will copy contexts below --
