cdd30ebb1b module: Convert symbol namespace to string literal
Clean up the existing export namespace code along the same lines of
commit 33def8498f ("treewide: Convert macro and uses of __section(foo)
to __section("foo")") and for the same reason, it is not desired for the
namespace argument to be a macro expansion itself.

a7a1c60bc4 drivers: iio: accel: adxl312 and adxl314 support
ADXL312 and ADXL314 are small, thin, low power, 3-axis accelerometers
with high resolution (13-bit) measurement up to +/-12 g and +/- 200 g
respectively.

Implement support for ADXL312 and ADXL314 by extending the ADXL313
driver.

fa4df5a903 iio:accel:adxl313: Move exports into IIO_ADXL313 namespace
In order to avoid unnecessary pollution of the global symbol namespace
move the driver core exports into their own namespace and import
that into the two bus modules.
