Subject: [PATCH] iio: sw_device: make the function argument as const

This is a follow-up patch for:
https://patchwork.kernel.org/patch/9999649/

Make the argument of the function iio_swd_group_init_type_name const as
it is only passed to the function config_group_init_type_name having the
argument as const.

This change allows a lot of config_item_type structures to be const.
