Test is giving problems in some networks. Could be that DNS server
is regarding repeated DNS enquiries on the test to be caused by
malfunctioning device.
Schedule the next OS tick inside of the ticker interrupt rather than
in the systick interrupt. Scheduling this while the ticker is
dispatching prevents an unnecissary rescheduling since this
rescheduling is done anyway when dispatching is finished.
This is particularly useful for the low power ticker on devices with
LPTICKER_DELAY_TICKS set to a non-zero value. This is because the low
power ticker cannot be reschduled immediately and needs to fall back
onto the microsecond ticker which temporarily locks deep sleep.
Note - the optimization in this commit is made possible by the commit:
"Don't reschedule ticker while dispatching"
Wait until dispatching is finished before scheduling the next ticker
interrupt. This prevents unnecissary calls to set_interrupt from
periodic elements being added back.

In order have a consistent return value for all methods in case of system is uninitialized
now also send and receive methods can return LORAWAN_STATUS_NOT_INITIALIZED.
The period of pwm we could get was limited to 69.9 ms, because prescaler value was set once only during initialization. base->mod is a 16 bit register, to get longer period we have to slow down the clk.
i2c_api implementation for NRF52 does a disable() followed by uninit().
The uniinit() implementation in NRF drivers layer makes another call to
disable. This throws off the state of the I2C instance leading to an
assert. Since the disable is only invoked from the I2C API layer for
Nordic, remove this redundant call.

RTX waits, such as sem.wait(N), delays for between N-1 and N cycles.
As lp_ticker is not so accurate as us_ticker,
sometines, wait is expiring just before the lp_timeout.
