Make sleep work again when BLE is disabled

Closes #231

See merge request !466

In commit 4944aa48 ("fix(ble): Update to changes from new SDK")
a call to `BbDrvDisable()` was added to `sleep_deepsleep()`.  This
function must, however, only be called when BLE was previously
initialized, otherwise a wakeup from deepsleep will not be possible (if
it ever reaches it?).

Fix this by reworking the BLE enabled check to also be usable here, to
only call `BbDrvDisable()` when BLE is active.

Add config option to disable low battery check

Closes #227

See merge request !464

We have encountered a device where the connection from the PMIC's ADMUX
pin to the MCUs ADC is severed and thus the low battery check would
trigger immediately.

For making such devices still usable, add a config option to disable the
low battery check entirely.

Fixes: #227

With sphinx 3 a ton of warnings about unresolvable xrefs are generated.
Add a workaround to silence them.

fix(sdk): Prevent endless loop on I2C error

Closes #226

See merge request !465

The read operation needs to wait until the stop bit it sends on error is
handled. Otherwise a following write operation will loop.

Closes #226

Ubuntu only ships clang 10 so python3-clang 11 is not working.  Fix it

BLE: Use synchronous BLE events and ATTC write queue

See merge request !455

Our interrupts are already scheduled via `mp_schedule()`. By switching
to the synchronous interface we avoid yet another `mp_schedule()` call
in the bluetooth module. This also allows the bluetooth module to not
have to use its internal ring buffer.
