[PATCH v2 16/19] staging: iio: resolver: ad2s1210: rename fexcit attribute

[David Lechner <dlechner@baylibre.com>]

This renames the fexcit attribute to excitation_frequency to be more
human-readable. Since we are already making many breaking changes to
the staging driver, this is a good time to do this.

Also make use of IIO_DEVICE_ATTR_RW while we are touching this.
