Having this structure defined static in the header lead to
unnecessary duplication and required additional symbol exports.
Use the EXPORT_NS_SIMPLE_DEV_PM_OPS() to clean this up in the same
fashion as many other drivers do this.

Up to now hmc5843_common_remove() returns zero unconditionally. Make it
return void instead which makes it easier to see in the callers that
there is no error to handle.
Also the return value of i2c and spi remove callbacks is ignored anyway.

To make code more readable, use a structure to express the channel
layout and ensure the timestamp is 8 byte aligned.
Found during an audit of all calls of uses of
iio_push_to_buffers_with_timestamp()
