[PATCH v2 1/2] staging: iio: isl29028: change sampling frequencies available to use decimals

[Brian Masney <masneyb@onstation.org>]

The sysfs attribute in_proximity_sampling_frequency_available currently
shows the values 1 3 5 10 13 20 83 100. These values are supposed to
correspond to the sleep values 800 400 200 100 75 50 12 0 (all in ms).
When passing in a sampling frequency of 3, it actually uses a sleep
time of 200ms instead of the expected 400ms value. This patch changes
the value shown by this sysfs attribute to use decimal numbers so
that the correct sampling frequency is shown to the user. Only the
integer portion is actually passed to isl29028_set_proxim_sampling(),
but that is ok since the correct sleep time will still be selected.
