Subject: [PATCH 2/3] IIO: dds.h convenience macros

From: Michael Hennerich <michael.hennerich@...log.com>

Changes since RFC/v1:
IIO: Apply list review feedback

Apply list review feedback:
	Rename attributes to fit IIO convention used in other drivers.
	Provide ddsX_out_enable as opposed to ddsX_out_disable.
	Fix typos.

Changes since v2:
IIO: dds.h: Apply more list review feedback

	Fix mixture of X and [n] notation for indices.
	Remove duplicated descriptions.
	Add store methods to some dds convenience macros.
