[PATCH v1 1/2] iio: core: Replace iio_sysfs_match_string_with_gaps() by __sysfs_match_string()

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

None of the current users is using gaps in the list of the items.
No need to have a specific function for that, just replace it by
library available __sysfs_match_string().
