pmic_init() uses the GPIO API internally to set up the PMIC
interrupt handler.  This does not work properly if called before
GPIO_Init() and will lead to the power-button never interrupting
Epicardium.

Fixes #83.

Delaying BLE startup by a bit seems to resolve the lockup issue we
observed.  This might need further attention in the future.

Without resetting the FPU we get spurious failures in Pycardium.  These
manifest in many different forms, ranging from HardFaults and triggered
assertions to "syntax errors" in loaded scripts while said script does
not contain any.

These failures stem from the FPU still containing state from the last
loaded payload and thus sometimes corrupting stack locations where the
previous payload had floating point state.

Closes #72.

This adds BLE a characteristic which allows to set the current time. The
time is set in milliseconds since 1.1.1970 as 64 bit value.
