Make the argument of the functions iio_sw{d/t}_group_init_type_name const
as they are only passed to the function config_group_init_type_name having
the argument as const.
Make the config_item_type structures const as they are either passed to
the functions having the argument as const or they are
stored in the const "ci_type" field of a config_item structure.

configfs_subsystem
This exported element needs to be accesible to all drivers using configfs
within IIO. Previously it was in the sw_trig.h file which only convered one
such usecase. This also fixes a sparse warning as it is now in a header
that makes sense to include from industrialio-configfs.c

A software trigger associates an IIO device trigger with a software
interrupt source (e.g: timer, sysfs). This patch adds the generic
infrastructure for handling software triggers.
Software interrupts sources are kept in a iio_trigger_types_list and
registered separately when the associated kernel module is loaded.
Software triggers can be created directly from drivers or from user
space via configfs interface.
To sum up, this dynamically creates "triggers" group to be found under
/config/iio/triggers and offers the possibility of dynamically
creating trigger types groups. The first supported trigger type is
"hrtimer" found under /config/iio/triggers/hrtimer.
