Andy Shevchenko ed3edc0909 iio: accel: mma9551: use NULL for GPIO connection ID
While using GPIO library API we might get into troubles in the future,
because we can't rely on label name in the driver since vendor firmware
might provide any GPIO pin there, e.g. "reset", and even mark it in _DSD
(in which case the request will fail).

To avoid inconsistency and potential issues we have two options:
a) generate GPIO ACPI mapping table and supply it via
acpi_dev_add_driver_gpios(), or
b) just pass NULL as connection ID.

The b) approach is much simpler and would work since the driver relies
on GPIO indices only. Moreover, the _CRS fallback mechanism, when
requesting GPIO, is going to be stricter, and supplying non-NULL
connection ID when neither _DSD, nor GPIO ACPI mapping is present, will
make request fail.
