Always crash on BHI260AP IRQ

[vsimionescu]

In the commit: d6f515c an always crash was added by this line from SensorBHI260AP.hpp:

static void handleISR()
{
*(bool *)(__data_available) = true;
}

as the definition of __data_available is: volatile bool SensorBHI260AP::__data_available;

so a bool is cast to bool * and than dereferenced.

Fix: change to __data_available = true;

Thank you for reminding me that this change was only done for compilation testing and not for hardware testing.
