cpu/nrf5x: Tolerate NULL callback in timers
...
timer_set has no documented restriction on this being not null, other
implementations explicitly tolerate it (rpx0xx checks inside the ISR,
but doing it at init time keeps the ISR slim).
This is useful when using a timer just to read, without any action when
it triggers (the action is taken depending on read values, eg. in a
thread context).

cpu/nrf5x_common: Implement timer_set()
...
The fallback implementation of timer_set() in `drivers/periph_common`
is known to fail on short relative sets. This adds a robust
implementation.

cpu/nrf5x_common/periph_timer: Fix thread safety
...
Two threads using distinct sets of channels should be able to share a
timer. Hence, we need to make read-modify-write accesses on timer state
atomic.

cpu/nrf5x_common/periph_timer: Clear periodic flag on set
...
A call to timer_set_absolute() should clear the periodic flag on the
specified timer and channel. This adds it.

For all currently supported platforms `unsigned long` is 32 bit in width. But
better use `uint32_t` to be safe.
