iio: accel: Support Kionix/ROHM KX022A accelerometer
KX022A is a 3-axis accelerometer from ROHM/Kionix. The sensor features
include variable ODRs, I2C and SPI control, FIFO/LIFO with watermark IRQ,
tap/motion detection, wake-up & back-to-sleep events, four acceleration
ranges (2, 4, 8 and 16g), and probably some other cool features.
Add support for the basic accelerometer features such as getting the
acceleration data via IIO. (raw reads, triggered buffer [data-ready] or
using the WMI IRQ).
Important things to be added include the double-tap, motion
detection and wake-up as well as the runtime power management.

module: Convert symbol namespace to string literal
Clean up the existing export namespace code along the same lines of
commit 33def8498fdd ("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.
