Subject: [PATCH RFC 1/6] iio: create accessor for iio_dev->scan_timestamp

"scan_timestamp" is supposed to be an internal member of the iio device
structure. However, there are some drivers that are using it directly.

For that reason, the following accessor is created:

	iio_is_soft_ts_enabled()

The goal of this accessor, is to ultimately mark "scan_timestamp" as
a __private member of the struct iio_dev.
